X0202MA 1BA2

**X02** 

1.25 A sensitive ate SCR g 

**==> picture [61 x 39] intentionally omitted <==**

## **Features** 

- on-state rms current: 1.25 A 

- repetitive peak off-state voltage: 600 V and 800 V 

- gate triggering current: 50 and 200 µA 

## **Applications** 

- ground fault circuit interrupters 

- overvoltage crowbar protection in power supplies 

- capacitive ignition circuits 

## **Description** 

The X02 SCR can be used as the on/off function in applications where topology does not offer high current for gate triggering. 

This device is optimized in forward voltage drop and inrush current capabilities for reduced power losses and high reliability in harsh environments.
