Question

52.The doping concentration of zener diode is ____ times of normal p-n junction diode :

Answer 1

Answer:

you can say approx 10 times

Explanation:

zener diodes have a highly doped p–n junction. A similar break down is observed in general purpose diodes (which might be quite high), but the voltage and sharpness of the knee is not clearly defined as in Zener diodes. Normal diodes are not designed to operate in the breakdown region and it can cause permanent failure of the device. Zener diodes are manufactured to operate reliably and quite precisely in this region, recovering fully from the junction breakdown and not being harmed in proper use.
