GENERAL DESCRIPTION
Glass passivated thyristors in a plastic
envelope, suitable for surface
mounting, 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 15 A/μs.
