3Q Hi-Com Triac

Rev.01 - 01 August 2024

Product data sheet

1. General description

Planar passivated high commutation three quadrant triac in a TO263 plastic package intended for

use in circuits where high static and dynamic dV/dt and high dI/dt can occur. This "series CT" triac will

commutate the full RMS current at the maximum rated junction temperature (T_j= 150 °C) without the

aid of a snubber. It is used in applications where "high junction operating temperature capability" is

required

2. Features and beneﬁts

•

3Q technology for improved noise immunity

•

High commutation capability with maximum false trigger immunity

High immunity to false turn-on by dV/dt

High junction operating temperature capability

High voltage capability

Less sensitive gate for high noise immunity

Planar passivated for voltage ruggedness and reliability

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

Rectiﬁer-fed DC inductive loads e.g. DC motors and solenoids
