General description

Planar passivated high commutation three quadrant triac in a SOT428 surface-mountable plastic package. This series B triac is intended for use in circuits where high static and dynamic dV/dt and high dI/dt can occur. The series B will commutate the full rated RMS current at the maximum rated junction temperature, without the aid of a snubber.

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 voltage capability

■ Planar passivated for voltage ruggedness and reliability

■ Surface-mountable package

■ Triggering in three quadrants only

Applications

■ Electronic thermostats

■ General purpose motor controls

■ Rectifier-fed DC inductive loads e.g. DC motors and solenoids
