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 high Tj operating capability and 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
• High surge capability
• High Tj(max)
• 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)
• High power motor controls
• Rectifier-fed DC inductive loads e.g. DC motors and solenoids
