General Description
◇ A sidac is a silicon bilateral voltage triggered switch,
   with greater power-handling capabilities than
   standard diacs. Upon application of a voltage
   exceeding the Sidac breakover voltage point, the Sidac
   switches on, through a negative resistance region, to a
   a low on-state voltage. Conduction will continue until
   the current is interrupted or drops below the minimum
   holding current of the device.
◇ Switching voltages in the range of 95 V to 330 V.
◇ Sidacs feature glass-passivated junctions that ensure
   long term reliability and stable characteristics by
   creating a rugged, reliable barrier against junction
   contamination.
◇ Variations of devices covered in this data sheet are
available for custom design applications. Please
   consult the factory for more information.
