As part of this family, the CPC1979 single-pole normally open (1-Form-A) Solid State Power Relay is rated for up to 3.5Arms continuous load current with a 5°C/W heat sink. The CPC1979 employs optically coupled MOSFET technology to provide 2500Vrms of input to output isolation. The optically coupled outputs, that use patented OptoMOS architecture, are controlled by a highly efficient infrared LED. The combination of low on-resistance and high load current handling capability makes this relay suitable for a variety of high performance switching applications. - Low Thermal Impedance: JC = 0.3 °C/W - Isolated, Low Thermal Impedance Ceramic Pad for Heat Sink Applications - Low Drive Power Requirements - Arc-Free With No Snubbing Circuits - No EMI/RFI Generation - Flammability Rating UL 94 V-0 ## **Applications** - Industrial Controls / Motor Control - Robotics The unique ISOPLUS-264 package pioneered by IXYS enables Solid State Relays to achieve the highest load current and power ratings. This package features a unique IXYS process in which the silicon chips are soft soldered onto the Direct Copper Bond (DCB) substrate instead of the traditional copper leadframe. The DCB ceramic, the same substrate used in high power modules, not only provides 2500Vrms isolation but also very low junction-to-case thermal impedance (0.3 °C/W). - Medical Equipment—Patient/Equipment Isolation - Instrumentation - Multiplexers - Data Acquisition **Ordering Information** - Electronic Switching - I/O Subsystems - Meters (Watt-Hour, Water, Gas) - Transportation Equipment - Aerospace/Defense ## **Approvals** - UL 508 Recognized Component: File E69938 ## **Pin Configuration** **Part Description** CPC1979J ISOPLUS-264 Package (25 per tube) ~~a~~ ## **Switching Characteristics** **==> picture [149 x 97] intentionally omitted <==** **----- Start of picture text -----**

For guaranteed parameters not indicated in the written specifications, please contact our application department. **www.ixysic.com** R10 5 **CPC1979** INTEGRATED CIRCUITS DIVISION ## **4 Manufacturing Information** ## **4.1 Moisture Sensitivity** All plastic encapsulated semiconductor packages are susceptible to moisture ingression. IXYS Integrated Circuits classifies its plastic encapsulated devices for moisture sensitivity according to the latest version of the joint industry standard, **IPC/JEDEC J-STD-020** , in force at the time of product evaluation. We test all of oy our products to the maximum conditions set forth in the standard, and guarantee proper operation of our devices when handled according to the limitations and information in that standard as well as to any limitations set forth in the information or standards referenced below. Failure to adhere to the warnings or limitations as established by the listed specifications could result in reduced product performance, reduction of operable life, and/or reduction of overall reliability. This product carries a **Moisture Sensitivity Level (MSL)** classification as shown below, and should be handled according to the requirements of the latest version of the joint industry standard **IPC/JEDEC J-STD-033** . **Device Moisture Sensitivity Level (MSL) Classification** CPC1979J MSL 1 ~~eS~~ ## **4.2 ESD Sensitivity** This product is **ESD Sensitive** , and should be handled according to the industry standard **JESD-625** . ## **4.3 Soldering Profile** Provided in the table below is the Classification Temperature (TC) of this product and the maximum dwell time the body temperature of this device may be (TC - 5)ºC or greater. The classification temperature sets the Maximum Body Temperature allowed for this device during lead-free reflow processes. For through-hole devices, and any other processes, the guidelines of **J-STD-020** must be observed. **Device Classification Temperature (TC) Dwell Time (tp) Max Reflow Cycles** CPC1979J 245°C 30 seconds 1 ~~————~~ ## **NOTE:** The exposed surface of the DCB substrate is not to be soldered. ## **4.4 Board Wash** IXYS Integrated Circuits recommends the use of no-clean flux formulations. Board washing to reduce or remove flux residue following the solder reflow process is acceptable provided proper precautions are taken to prevent damage to the device. These precautions include but are not limited to: using a low pressure wash and providing a follow up bake cycle sufficient to remove any moisture trapped within the device due to the washing process. Due to the variability of the wash parameters used to clean the board, determination of the bake temperature and duration necessary to remove the moisture trapped within the package is the responsibility of the user (assembler). Cleaning or drying methods that employ ultrasonic energy may damage the device and should not be used. Additionally, the device must not be exposed to flux or solvents that are Chlorine- or Fluorine-based. ## e3 R10 **www.ixysic.com** 6 **CPC1979** INTEGRATED CIRCUITS DIVISION **4.5 Mechanical Dimensions** **==> picture [486 x 327] intentionally omitted <==** **----- Start of picture text -----**
