• ASCR — Asymmetrical SCR
• BCT — Bidirectional Control Thyristor — A bidirectional switching device containing two thyristor structures with separate gate contacts
• BOD — Breakover Diode — A gateless thyristor triggered by avalanche current
  • DIAC — Bidirectional trigger device
  • Dynistor — Unidirectional switching device
  • Shockley diode — Unidirectional trigger and switching device
  • SIDAC — Bidirectional switching device
  • Trisil, SIDACtor — Bidirectional protection devices
