Product data sheet
1. 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 CT" triac will commutate the full RMS current at the
maximum rated junction temperature (Tj = 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 immunity to false turn-on by dV/dt
• High junction operating temperature capability
• High voltage capability
• Less sensitive gate for high noise immunity
• Planar passivated for voltage ruggedness and reliability
• Triggering in three quadrants only
3. Applications
• Applications subject to high temperature
• 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
