Product data sheet

1. General description

Planar passivated high commutation three quadrant triac in a TO220F "full pack" 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

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

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

• High voltage capability

• Isolated mounting base package

• Less sensitive gate for very high noise immunity

• Planar passivated for voltage ruggedness and reliability

• Triggering in three quadrants only

3. Applications

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

• 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
