General description

Planar passivated high commutation three quadrant triac in a SOT78D (TO-220AB) internally insulated plastic package intended for use in circuits where high static and dynamic dV/dt and high dI/dt can occur. This series C triac will commutate the full RMS current at the maximum rated junction temperature without the aid of a snubber. This device has an internally isolated mounting base.

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

• Isolated mounting base with 2500 V (RMS) isolation

• Less sensitive gate for high noise immunity

• Planar passivated for voltage ruggedness and reliability

• Triggering in three quadrants only

Applications

• Electronic thermostats (heating and cooling)

• Motor controls

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