3Q Hi-Com Triac
13 September 2018
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 B" triac will commutate the full RMS current at the maximum rated junction temperature
without the aid of a snubber.
2. 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
3. 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
