Voltage activation of this solid state switch is accomplished
withꢀpeakꢀvoltageꢀlevelꢀofꢀ190ꢀtoꢀ260Volts.ꢀTheꢀSIDACꢀisꢀ
a silicon bilateral voltage triggeredThyristor switch that
switches on through a negative resistance region to a low
on-state voltage. Conduction will continue until current is
interrupted or lowered below minimum holding current of
the device.
