Quand un redresseur commandé au silicium ("SCR") est déclenché, à quelle autre diode à semi-conducteur ressemblent ses caractéristiques électriques (mesurées entre l'anode et la cathode)?

  1. ADiode à jonction
  2. BDiode PIN
  3. CDiode Schottky ("hot carrier")
  4. DDiode varactor

Correct answer: A — Diode à jonction. Question tirée de la banque officielle d'ISDE.

Why

Once triggered, a silicon controlled rectifier acts like a standard junction diode, allowing current to flow freely from anode to cathode while blocking it in the reverse direction. The full explanation — and one for every question — is in Pro.
