Thyristors
BT151U series C
GENERAL 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 15 A/µs.
