Answer Posted / chaitanya

it is right that zener diode is used in reversed
biased,but in forward bias it act same as normal diode.

if u want to use it in rectifier it can be used provided
that its value shud be gr8er than PIV(there will be no
reverse breakdown).
it is not used becoz of cost (normal diode-50Ps. zener
-frm Rs.2 onwards depends on value)
