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 (T
j
= 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 sensitve 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
