Zener Diodes

The Zener Diode is a special diode which can

• operate in forward bias only

• operate in reverse bias only

• operate in both forward bias and reverse bias

The forward bias operation of the Zener diode is the same as that of a usual semi-conductor diode.

• True

• False

The Zener current is

• the current flowing through the Zener diode while in reverse bias.

• the current directed away from the Zener diode.

• the current required to turn off the Zener diode.
