1. Product profile
1.1 General description
Passivated high commutation 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. These
devices will commutate the full rated RMS current at the maximum rated junction
temperature, without the aid of a snubber.
1.2 Features
a73 High maximum junction temperature
a73 High commutation capability
1.3 Applications
a73 Motor control
a73 Industrial and domestic heating
1.4 Quick reference data
