High temperature 20 A Snubberless™ Triacs

Features

■ Medium current Triac

■ 150 °C max. T

■ 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).
