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
The width of the depletion and the doping levels
