Thyristor - Types of Thyristor

Types of Thyristor

  • 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
  • GTO — Gate Turn-Off thyristor
  • ETO — Emitter Turn-Off Thyristor
  • IGCT — Integrated Gate Commutated Thyristor
    • DB-GTO — Distributed Buffer Gate Turn-Off thyristor
    • MA-GTO — Modified Anode Gate Turn-Off thyristor
  • 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.
  • BRT — Base Resistance Controlled Thyristor
  • RCT — Reverse Conducting 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
  • 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

Famous quotes containing the words types of and/or types:

    Our children evaluate themselves based on the opinions we have of them. When we use harsh words, biting comments, and a sarcastic tone of voice, we plant the seeds of self-doubt in their developing minds.... Children who receive a steady diet of these types of messages end up feeling powerless, inadequate, and unimportant. They start to believe that they are bad, and that they can never do enough.
    Stephanie Martson (20th century)

    Science is intimately integrated with the whole social structure and cultural tradition. They mutually support one other—only in certain types of society can science flourish, and conversely without a continuous and healthy development and application of science such a society cannot function properly.
    Talcott Parsons (1902–1979)
