General description

Planar passivated high commutation three quadrant triac in a SOT78 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.

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

• Less sensitive gate for very high noise immunity

• Planar passivated for voltage ruggedness and reliability

• Triggering in three quadrants only

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
