Product data sheet

1. General description

Planar passivated high commutation three quadrant triac in a TO252 (DPAK) surface mountable

plastic package. This triac balances the requirements of commutation performance and

gate sensitivity and is intended for interfacing with low power drivers and logic ICs including

microcontrollers. This "series ET" triac will commutate the full rated RMS current at the maximum

rated junction temperature (Tj(max) = 150 °C) without the aid of a snubber.

2. Features and benefits

• High voltage capability

• High commutation capability with maximum false trigger immunity

• Direct interfacing with low level power drivers and logic ICs

• High junction operating temperature capability (Tj(max) = 150 °C)

• Planar passivated for voltage ruggedness and reliability

• Triggering in three quadrants only

• Sensitive gate for easy logic level triggering

• Surface mountable package

3. Applications

• Compressor starting control circuits

• General purpose motor controls

• Reversing induction motor controls e.g. vertical axis washing machines

• Applications subject to high temperature (Tj(max) = 150 °C)
