## **Features** 

- 5A Load Current with 5°C/W Heat Sink 

- Low 0.35 On-Resistance 

## **Description** 

The CPC1968 single-pole normally open (1-Form-A) Solid State Power Relay is rated for up to 5A continuous load current with a 5°C/W heat sink. 

Optically coupled MOSFET technology enables the CPC1968 to provide 2500Vrms of input to output isolation. The output, constructed with efficient MOSFET switches and photovoltaic die, uses IXYS Integrated Circuits’ patented OptoMOS architecture while the input, a highly efficient infrared LED, provides the optically coupled control. The combination of low on-resistance and high load current handling capability makes this relay suitable for a variety of high performance switching applications. 

- 500VP Blocking Voltage 

- 2500Vrms Input/Output Isolation 

- 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** 

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).

## **2.1 Thermal Management** 

Device high current characterization was performed using Kunze heat sink KU 1-159, phase change thermal interface material KU-ALC 5, and transistor clip KU 4-499/1. This combination provided an approximate junction-to-ambient thermal impedance of 12.5°C/W. 

## **2.2 Heat Sink Calculation** 

Higher load currents are possible by using lower thermal impedance heat sink combinations. 

## **Heat Sink Rating** 

**==> picture [145 x 37] intentionally omitted <==**

- TJ = Junction Temperature (°C), TJ ≤ 110°C * 

- TA = Ambient Temperature (°C) 

- IL(99) = Load Current with Case Temperature @ 99°C (ADC) 

- IL = Desired Operating Load Current (ADC), IL ≤ IL(MAX) 

- θ JC = Thermal Impedance, Junction to Case (°C/W) = 0.3°C/W 

- θ CA = Thermal Impedance of Heat Sink & Thermal Interface Material , Case to Ambient (°C/W) 

- PD(99) = Maximum power dissipation with case temperature held at 99ºC = 31W 

- Elevated junction temperature reduces semiconductor lifetime. 

**NOTE:** The exposed surface of the DCB substrate is not to be soldered.

## **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**<br>~~eS~~|**Moisture Sensitivity Level (MSL) Classification**<br>~~eS~~|
|---|---|
|CPC1968J<br>~~eS~~|MSL 1<br>~~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** CPC1968J 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.
