The SIDAC is a silicon unilateral voltage triggered switch. 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.

SIDACs feature glass-passivated junctions to ensure a rugged and dependable device capable of withstanding harsh environments. 

Features:

  • Rectified AC/DC Circuit Oriented
  • Triggering Voltage of 75V to 260V
  • RoHS Compliant

Applications:

  • Suitable for capacitor-discharge HV generator circuit
