BL GALAXY ELECTRICAL KG --- SERIES SIDAC VBO: 95 - 280 Volts 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.
