Quelle est la principale caractéristique de la diode Zener?

  1. AUn courant constant malgré les variations de tension
  2. BUne région de résistance négative
  3. CUne capacité interne qui varie selon la tension appliquée
  4. DUne tension constante malgré les variations de courant

Correct answer: D — Une tension constante malgré les variations de courant. Question tirée de la banque officielle d'ISDE.

Why

A Zener diode is designed to maintain a steady voltage across its terminals even when the current flowing through it changes significantly, making it ideal for voltage regulation. The full explanation — and one for every question — is in Pro.
