GENERAL DESCRIPTION
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/µs.

Note: Operation above 110˚C may require the use of a gate to cathode resistor of 1kΩ or less.
