3Q Hi-Com Triac

Rev.02 - 29 April 2019

Product data sheet

1. General description

Planar passivated high commutation three quadrant triac in a TO263 (D2PAK) surface mountable

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

gate sensitivity and is intended for interfacing with low power drivers including microcontrollers. It is

used in applications where "high junction operating temperature" capability is required.

2. Features and benefits

• 3Q technology for improved noise immunity

• Direct interfacing with low power drivers and microcontrollers

• Good immunity to false turn-on by dV/dt

• High commutation capability with sensitive gate

• High junction operating temperature capability

• High voltage capability

• Planar passivated for voltage ruggedness and reliability

• Sensitive gate for easy logic level triggering

• Surface mountable package

• Triggering in three quadrants only

3. Applications

• Applications subject to high temperature

• Electronic thermostats (heating and cooling)

• High power motor controls e.g. washing machines and vacuum cleaners

• Refrigeration and air-conditioner compressor controls
