Glass passivated, sensitive gate thyristor in
a plastic envelope, suitable for surface
mounting, intended for use in general
purpose switching and phase control
applications. These devices feature a
gate-cathode reverse breakdown voltage
specification. They can 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.
