## Sensitive gate 4 A SCRs 

Datasheet - production data 

## **Description** 

Thanks to highly sensitive triggering levels, the device is suitable for all applications where the available gate current is limited, such as motor control for hand tools, kitchen aids, overvoltage crowbar protection for low power supplies among others. 

Available in through-hole and surface-mount packages, they provide an optimized performance in a limited space area.
