Qu'est-ce qui limite le courant maximal en polarisation directe d'une diode à jonction?
- ALa tension directe
- BLa force contre-électromotrice
- CLa tension inverse de crête
- DLa température de la jonction
Correct answer: D — La température de la jonction. Question tirée de la banque officielle d'ISDE.
Why
A junction diode stops working if it gets too hot because the heat builds up inside the tiny junction where the materials meet. The full explanation — and one for every question — is in Pro.
