Product specification
Thyristors
logic level
GENERAL DESCRIPTION
Glass passivated, sensitive gate
thyristors in a plastic envelope,
intended for use in general purpose
switching
and
phase
control
applications. These devices are
intended to be interfaced directly to
microcontrollers, logic integrated
circuits and other low power gate
trigger circuits.

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