In addition to superior operating performance at rated 150°C (AEC–Q200 compliance) they offer excellent transient energy absorption due to improved energy volume distribution and power dissipation. ## **Applications** Typical applications include transient over-voltage protection in automotive assembly motors and controllers as well as surge protection of non-automotive electronic products exposed to over-heating, i.e., consumer, telecommunication or industrial. Load dump and jump start protection of 12 to 24 V supply systems. Protection of integrated circuits and other components at the circuit board level including the suppression of inductive switching or other transient events such as surge voltage. ESD protection for components sensitive to IEC 1000–4–2, MILSTD 883C Method 3015.7 and other industry spec. Replacement of larger surface mount TVS Zeners in many applications. Designed to achieve electromagnetic compliance of end products and provide on-board transient voltage protection of ICs and transistors. ## **Benefits** - AEC-Q200 qualified Grade 1 - Surface mount form factor - Operating ambient temperature of −55°C to +150°C - Superior operating performance rated at 150°C (AEC-Q200 compliance) - Operating voltage range of 11 – 170 V - AC voltage range (Vrms) of 8 – 130 V - High resistance to cyclic temperature stress - Low leakage currents after 1,000 hours rated at 150°C - High energy absorption capability - Available case sizes: 0603, 0805, 1206, 1210, 1812, 2220 - Short response time - Broad range of current and energy handling capabilities - Low clamping voltage – Uc - Non-sensitive to mildly activated fluxes - Barrier type end terminations solderable with Pb-free solders according to JEDEC J–STD–020C and IEC 60068–2–58 - RoHS 2 2011/65/EC, REACH compliant ~~_~~ **Built Into Tomorrow** © KEMET Electronics Corporation • KEMET Tower • One East Broward Boulevard Fort Lauderdale, FL 33301 USA • 954-766-2800 • www.kemet.com V0003_VE • 7/21/2021 1 SMD Varistors VE High Temperature 150°C ## **Ordering Information** **==> picture [542 x 57] intentionally omitted <==** **----- Start of picture text -----**

The mean life of series components is a function of: - Factor of Applied Voltage - Ambient temperature Mean life is closely related to Failure rate (formula). Mean life (ML) is the arithmetic mean (average) time to failure of a component. Failure rate is the frequency with which an engineered system or component fails, expressed for example in failures per hour. Failure rate is usually time dependent, an intuitive corollary is that the rate changes over time versus the expected life cycle of a system. ## **Mean Life on Arrhenius model** ## **Failure rate formula – calculation** _10_[9] _Λ= [fit] ML[h]_ ## **FAV – Factor of Applied Voltage** _Vapl Λ= V max_ Vapl = applied voltage Vmax = maximum operating voltage **==> picture [253 x 184] intentionally omitted <==** **----- Start of picture text -----**

Both processes can be performed with Pb-containing or Pb-free solders. The termination option available for these soldering techniques is Barrier Type End Terminations. |**End Termination**|**Designation**|**Recommended and**
**Suitable for**|**Component RoHS**
**Compliant**| |---|---|---|---| |Ni Sn Barrier Type End
Termination|Ni R1|Pb-containing and
Pb-free soldering|Yes| **Wave Soldering** – this process is generally associated with discrete components mounted on the underside of printed circuit boards, or for large top-side components with bottom-side mounting tabs to be attached, such as the frames of transformers, relays, connectors, etc. SMD varistors to be wave soldered are first glued to the circuit board, usually with an epoxy adhesive. When all components on the PCB have been positioned and an appropriate time is allowed for adhesive curing, the completed assembly is then placed on a conveyor and run through a single, double wave process. **Infrared Reflow Soldering** – these reflow processes are typically associated with top-side component placement. This technique utilizes a mixture of adhesive and solder compounds (and sometimes fluxes) that are blended into a paste. The paste is then screened onto PCB soldering pads specifically designed to accept a particular sized SMD component. The recommended solder paste wet layer thickness is 100 to 300 µm. Once the circuit board is fully populated with MD components, it is placed in a reflow environment, where the paste is heated to slightly above its eutectic temperature. When the solder paste reflows, the SMD components are attached to the solder pads. **Solder Fluxes** – solder fluxes are generally applied to populated circuit boards to clean oxides forming during the heating process and to facilitate the flowing of the solder. Solder fluxes can be either a part of the solder paste compound or can be separate materials, usually fluids. Recommended fluxes are: - Non-activated (R) fluxes, whenever possible - Mildly activated (RMA) fluxes of class L3CN - Class ORLO **Activated (RA),** water soluble or strong acidic fluxes with a chlorine content > 0.2 wt. % are NOT RECOMMENDED. The use of such fluxes could create high leakage current paths along the body of the varistor components. When a flux is applied prior to wave soldering, it is important to completely dry any residual flux solvents prior to the soldering process. **Thermal Shock** – to avoid the possibility of generating stresses in the varistor chip due to thermal shock, a preheat stage to within 100°C of the peak soldering process temperature is recommended. Additionally, SMD varistors should not be subjected to a temperature gradient greater than 4°C/second, with an ideal gradient being 2°C/second. Peak temperatures should be controlled. Wave and Reflow soldering conditions for SMD varistors with Pb-containing solders are shown in Fig. 1 and 2 respectively, while Wave and Reflow soldering conditions for SMD varistors with Pb-free solders are shown in Figures 1 and 3 © KEMET Electronics Corporation • KEMET Tower • One East Broward Boulevard Fort Lauderdale, FL 33301 USA • 954-766-2800 • www.kemet.com V0003_VE • 7/21/2021 8 SMD Varistors VE High Temperature 150°C ## **Soldering cont.** Whenever several different types of SMD components are being soldered, each having a specific soldering profile, the soldering profile with the least heat and the minimum amount of heating time is recommended. Once soldering has been completed, it is necessary to minimize the possibility of thermal shock by allowing the hot PCB to cool to less than 50°C before cleaning. **Inspection Criteria** – the inspection criteria to determine acceptable solder joints, when Wave or Infrared Reflow processes are used, will depend on several key variables, principally termination material process profiles. **Pb-contining Wave and IR Reflow Soldering** – typical “before” and “after” soldering results for Barrier Type End Terminations can be seen in Fig. 4. Barrier type terminated varistors form a reliable electrical contact and metallurgical bond between the end terminations and the solder pads. The bond between these two metallic surfaces is exceptionally strong and has been tested by both vertical pull and lateral (horizontal) push tests. The results exceed established industry standards for adhesion. The solder joint appearance of a barrier type terminated varistor shows that solder forms a metallurgical junction with the thin tin-alloy (over the barrier layer), and due to its small volume “climbs” the outer surface of the terminations, the meniscus will be slightly lower. This optical appearance should be taken into consideration when programming visual inspection of the PCB after soldering. ## **Ni Sn Barrier Type End Terminations** Figure 4: Soldering Criterion in case of Wave and IR Reflow Pb-containing Soldering **Pb-free Wave and IR Reflow Soldering** – typical “before” and “after” soldering results for Barrier Type End Terminations are given in a phenomenon knows as “mirror” or “negative” meniscus. Solder forms a metallurgical junction with the entire volume of the end termination, i.e. it diffuses from pad to end termination across the inner side, forming a “mirror” or “negative” meniscus. The height of the solder penetration can be clearly seen on the end termination and is always 30% higher than the chip height. © KEMET Electronics Corporation • KEMET Tower • One East Broward Boulevard Fort Lauderdale, FL 33301 USA • 954-766-2800 • www.kemet.com V0003_VE • 7/21/2021 9 SMD Varistors VE High Temperature 150°C ## **Soldering cont.** **Solder Test and Retained Samples** – reflow soldering test based on J-STD-020D.1 and soldering test by dipping based on IEC 600682 for Pb-free solders are preformed on each production lot as shown in the following chart.

If no other means of rework is available, the following criteria must be strictly followed: - Do not allow the tip of the iron to directly contact the top of the chip - Do not exceed the following soldering iron specifications: Output Power: 30 Watts maximum Temperature of Soldering Iron Tip: 280°C maximum Soldering Time: 10 Seconds maximum **Storage Conditions** – SMD varistors should be used within 1 year of shipment from factory to avoid possible soldering problems caused by oxidized terminals. The storage environment should be controlled, with humidity less than 40% and temperature between -25 and 45 °C. Varistor chips should always be stored in their original packaged unit. © KEMET Electronics Corporation • KEMET Tower • One East Broward Boulevard Fort Lauderdale, FL 33301 USA • 954-766-2800 • www.kemet.com V0003_VE • 7/21/2021 10 SMD Varistors VE High Temperature 150°C ## **Soldering Pad Configuration** **==> picture [335 x 123] intentionally omitted <==** **----- Start of picture text -----**
