GENERAL DESCRIPTION
Glass passivated, sensitive gate
triacs in a plastic envelope, intended
for use in general purpose
bidirectional switching and phase
control applications, where high
sensitivity is required in all four
quadrants.

Although not recommended, off-state voltages up to 800V may be applied without damage, but the triac may
switch to the on-state. The rate of rise of current should not exceed 15 A/µs.
