Product Description

Product Description

The SIDAC is a silicon bilateral voltage-triggered switch designed for AC circuit applications. It switches on when the applied voltage exceeds its breakover voltage, transitioning through a negative resistance region to a low on-state voltage. Conduction is maintained until the current is interrupted or falls below the minimum holding current. Featuring glass-passivated junctions, these SIDACs offer a rugged and dependable solution for harsh environments. They are suitable for high voltage power supplies, natural gas igniters, high-pressure sodium lamps, and Xenon flash ignition.

Product Attributes

  • Brand: Teccor
  • Type: Standard Bidirectional SIDACs
  • Certifications: RoHS Compliant
  • Material: UL recognized epoxy meeting flammability classification 94V-0
  • Terminal Finish: 100% Matte Tin Plated / Pb-free Solder Dipped
