## High temperature 12 A Snubberless™ Triacs 

## **Features** 

- Medium current Triac 

- 150 °C max. T turn-off commutation j 

- Low thermal resistance with clip bonding 

- Very high 3 quadrant commutation capability 

- Packages are RoHS (2002/95/EC) compliant 

- UL certified (ref. file E81734) 

## **Applications** 

Especially designed to operate in high power density or universal motor applications such as vacuum cleaner and washing machine drum motor, these 12 A Triacs provide a very high switching capability up to junction temperatures of 150 °C. 

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

## **Description** 

Available in through-hole or surface mount packages, the T1235H and T1250H Triac series are suitable for general purpose mains power ac switching. 

By using an internal ceramic pad, the T12xxH-6I provides voltage insulation (rated at 2500 V rms).
