DO-15X Axial Lead DO-214AA Surface Mount TO-202AB Type 1 Do not use mounting tab or center lead, electrically connected TO-92 Type 70 SIDAC (95 - 330 Volts) 9 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 will continue until the current is interrupted or drops below the minimum holding current of the device.
