Types of thyristor

  • SCR — Silicon Controlled Rectifier
  •  
  • ASCR — Asymmetrical SCR
  •  
  • RCT — Reverse Conducting Thyristor
  •  
  • LASCR — Light Activated SCR, or LTT — Light Triggered Thyristor
  •  
  • DIAC & SIDAC — Both forms of trigger devices
  •  
  • BOD — Breakover Diode — A gateless thyristor triggered by avalanche current, used in protection applications
  •  
  • TRIAC — Triode for Alternating Current — A bidirectional switching device containing two thyristor structures
  •  
  • GTO — Gate Turn-Off thyristor
  •  
  • IGCT — Integrated Gate Commutated Thyristor

MA-GTO — Modified Anode Gate Turn-Off thyristor

           DB-GTO — Distributed Buffer Gate Turn-Off thyristor

  • MCT — MOSFET Controlled Thyristor — It contains two additional FET structures for on/off control.
    •  

BRT — Base Resistance Controlled Thyristor

  •  
  • SITh — Static Induction Thyristor, or FCTh — Field Controlled Thyristor containing a gate structure that can shut down anode current flow
