## **Features** 

Especially designed to operate in high power density or universal motor applications such as vacuum cleaner and washing machine drum motor, these 8 A Triacs provide a very high switching capability up to 150 °C junction temperatures. 

The heatsink can be reduced, compared to traditional Triac, according to the high performance at given junction temperatures. 

## **Description** 

Available in through-hole or surface mount packages, these Triacs series are suitable for general purpose mains power ac switching. 

By using an internal ceramic pad, they provide voltage insulation (rated at 2500 VRMS).
