What is called Zener effect?
It occurs in a reverse biased p-n diode when the electric field enables tunneling of electrons from the valence to the conduction band of a semiconductor, leading to numerous free minority carriers which suddenly increase the reverse current.

See lessWhat is an avalanche current?
When a voltage exceeds breakdown voltage of a MOSFET, breakdown phenomena occurs and current flows. It's called “Avalanche break down”, the current flowing at that time is called avalanche current, and the energy applied to the MOSFET is called avalanche energy.

See lessWhat is the main cause of Zener?
The main cause of zener breakdown is high doping concentrations. The breakdown is a condition when upon increasing the voltage in small amounts; we experience a massive current flow in the device. Zener breakdown occurs when we apply reverse bias to a heavily doped diode.

See lessWhy is it called Zener diode?
A Zener diode is a special type of semiconductor diode that operates under reverse bias conditions. In simpler terms, it conducts electricity when the current flows in the opposite direction of a regular diode. It is named after Clarence Melvin Zener, who first described the electrical properties ofRead more

See lessWhat is zero bias?
Zero bias: No external voltage is applied to the P-N junction diode. Forward bias: The positive terminal of the voltage potential is connected to the p-type while the negative terminal is connected to the n-type.

See lessDo diodes convert AC to DC?
Rectification: Set up diodes in a bridge configuration. This bridge will convert the AC, whether stepped down or directly from the source, into a pulsating DC once the system is powered on. Smoothing: After the diode bridge, connect capacitors. They help in converting the pulsating DC to a smootherRead more
