Zener Diode

depletion region

In Zener breakdown, the ________ will retain back once the reverse voltage has been removed.

Zener diodes

________ have the property of maintaining low voltages even though high voltages are applied and hence make nice voltage regulators.

basic diode

In the ________, a junction is formed due to the interaction of p- type and n- type.

reverse saturation

The current generated because of the minority charge is referred to as ________ current and this is responsible for the occurrence of avalanche breakdown.

Zener Diode

Special type of diode designed to reliably allow current to flow backwards

Zener Breakdown

The process in which electrons move across the barrier from the valence band of p-type material to the conduction band of n-type material.

Avalanche Breakdown

________ is a phenomenon that can occur in both insulating and semiconducting materials.

Zener Voltage

The voltage that is sufficient for the reverse breakdown condition thus allowing the diode to conduct in reverse direction

Zener Current

The maximum current that can flow through a Zener diode at a rated voltage

Breakdown voltage of a diode

depends on the amount of doping

After breakdown, the flow of the current in the circuit

tends to increase immediately

Applications of zener diode

Ammeter, voltmeter, ohmmeter

Movement during reverse bias

noticed due to minority carriers
