GENERAL DESCRIPTION
Glass 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.
