K2xx0yHU Series
Description
ThenewK2xx0yHUisahigherenergySIDACswitchforgas
ignitionapplicationsrequiringhighercurrentpulsecurrent
especiallyatlowrepetitionrate.ItisofferedinaDO-15
leadedpackageandDO-214AAsurfacemountpackage.
Voltage activation of this solid state switch is accomplished
withpeakvoltagelevelof190to260Volts.TheSIDACis
a silicon bilateral voltage triggered Thyristor 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.
