DESCRIPTION

Passivated thyristors in a plastic envelope, intended for use in

applications requiring high bidirectional blocking voltage

capability and high thermal cycling performance. Typical

applications include motor control, industrial and domestic

lighting, heating and static switching.

*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 15A/

µs.
