T2035H, T2050H

High temperature 20 A Snubberless™ Triacs

Features

■Medium current Triac

■150 °C max. Tj turn-off commutation

■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.

Description

Available in through-hole and surface mount packages, the T2035H and T2050H Triac series are suitable for general purpose mains power AC switching.

These 20 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.

By using an internal ceramic pad, the T20xxH-6I provides voltage insulation (rated at 2500 V rms).
