The transfer characteristics of zener and pn diode looks same in reverse bias, i have asked few why in many rectifier circuits zener is used.i got answer like, it wont burn up in high reverse current like pn diode . why zener is special than pn diode.

Hi Bhuvanesh,

I have here pdf arcticles concerning pn junction and zener diodes.

1. PN Junction and Zener Diode.
2. PN and Metal–Semiconductor Junctions .

You could also see this youtube video about their characteristic curves.

Hope it helps,
