STC SIDAC Series DO-15X DO-214 Surface Mount TO-92 Type 70 TO-202 E9 General Description The 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 low on-state voltage. Conduction continues until the current is interrupted or drops below the minimum holding current of the device. Suntac’s sidacs feature glass-passivated junctions to ensure a rugged and dependable device capable of withstanding harsh environments. Variations of devices covered in this data sheet are available for custom design applications. Consult the factory for more information.
