Thyristor have many types:



AGT – Anode Gate Thyristor – A thyristor with gate on n-type layer near to the anode

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

BRT – Base Resistance Controlled Thyristor

ETO – Emitter Turn-Off Thyristor[9]

GTO – Gate Turn-Off thyristor

DB-GTO – Distributed buffer gate turn-off thyristor

MA-GTO – Modified anode gate turn-off thyristor

IGCT – Integrated gate-commutated thyristor

Ignitor – Spark generators for fire-lighter ckts

LASCR – Light-activated SCR, or LTT – light-triggered thyristor

LASS – light-activated semiconducting switch

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

CSMT or MCS – MOS composite static induction thyristor

PUT or PUJT – Programmable Unijunction Transistor – A thyristor with gate on n-type layer near to the anode used as a functional replacement for unijunction transistor

RCT – Reverse Conducting Thyristor

SCS – Silicon Controlled Switch or Thyristor Tetrode – A thyristor with both cathode and anode gates

SCR – Silicon Controlled Rectifier

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

TRIAC – Triode for Alternating Current – A bidirectional switching device containing two thyristor structures with common gate contact

Quadrac – special type of thyristor which combines a DIAC and a TRIAC into a single package.
