General description

Planar passivated high commutation three quadrant triac in a SOT78 (TO-220AB) plastic package intended for use in circuits where high static and dynamic dV/dt and high dI/dt can occur. This series B triac will commutate the full RMS current at the maximum rated junction temperature without the aid of a snubber.

Features and benefits

• 3Q technology for improved noise immunity

• High commutation capability with maximum false trigger immunity

• High voltage capability

• Less sensitive gate for highest noise immunity

• Planar passivated for voltage ruggedness and reliability

• Triggering in three quadrants only

• Very high immunity to false turn-on by dV/dt

Applications

• 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
