## **Features** 

- Load Current up to 250mArms 

- 800VP Blocking Voltage 

- 5mA Sensitivity 

## **Description** 

The CPC1972 is an AC Solid State Switch using optical coupling with dual power silicon controlled rectifier (SCR) outputs to produce an alternative to optocoupler and Triac circuits. The CPC1972 switches are robust enough to provide a blocking voltage of up to 800V . P 

In addition, tightly controlled zero cross circuitry ensures switching of AC loads without the generation of transients. 

- Zero-Crossing Detection 

- DC Control, AC Output 

- Optically Isolated 

- Low EMI and RFI Generation 

- High Noise Immunity 

- Flammability Rating UL 94 V-0 

## **Applications** 

- Programmable Control 

- Process Control 

- Power Control Panels 

The input and output circuits are optically coupled to provide 3750Vrms of isolation and noise immunity between the control and load circuits. As a result the CPC1972 is well suited for industrial environments where electromagnetic interference could disrupt the operation of electromechanical relays.

## **Manufacturing Information** 

## **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 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>~~———————~~|**Moisture Sensitivity Level (MSL) Classifi cation**<br>~~———————~~|

|CPC1972G / CPC1972GS<br>~~———————~~|MSL 1<br>~~———————~~|



## **ESD Sensitivity** 

This product is **ESD Sensitive** , and should be handled according to the industry standard **JESD-625** . 

## **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 Classifi cation Temperature (Tc) Dwell Time (tp) Max Refl ow Cycles** CPC1972G 250ºC 30 seconds 1 CPC1972GS 250ºC 30 seconds 3 ~~pp~~ **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.
