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.
SYMBOL
ABSOLUTE MAXIMUM RATINGS.
Repetitive peak off-state voltages
Average on-state current
(half sine wave; T
RMS on-state current (all conduction angles)
Non-repetitive peak on-state current
(half sine wave; T
t = 10 ms
t = 8.3 ms
I
Repetitive rate of rise of on-state current after triggering
(I
Peak gate current
Peak gate voltage
Peak reverse gate voltage
Peak gate power (over any 20 ms period)
Average gate power
Storage temperature
Operating junction temperature
*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.
