Why can a diode be damaged by a very high reverse-bias voltage? What does this reveal about its physical limits?

ریورس بایس میں بہت زیادہ وولٹیج ڈائیوڈ کو کیوں نقصان پہنچا سکتا ہے؟ اس سے آلے کی طبعی حدود کے بارے میں کیا معلوم ہوتا ہے؟

Solution & explanation

Breakdown permits large current; without current limiting, excessive heating can damage the junction. A breakdown voltage is a device rating, and specially designed diodes can operate there within limits.
