How is zener diode connected in a circuit?
Answers
Zener diode is a special purpose p-n junction semiconductor diode. It
is a heavily doped diode. Zener invented this diode. Zener
diode operates in the breakdown region in the reverse bias. Its main
function is to regulate voltage. It allows a wide range of currents
almost at the same voltage.
Zener diode is connected in reverse bias in a circuit, for regulating
voltage. It is also called a shunt regulator. Zener is a control in many
electronic circuits.
It is connected in reverse across the load (electrical appliance
like refrigerator ). Its resistance is very high till the breakdown voltage is
reached. Zener breaks down near the operating voltage of the appliance and
does not allow any change in the voltage across the load. Near the zener
breakdown voltage, its resistance is very low.
See the diagram for the characteristics.
Explanation:
references and as shunt regulators to regulate the voltage across smallcircuits. When connected in parallel with a variable voltage source so that it is reverse biased, a Zener diode conducts when the voltage reaches the diode'sreverse breakdown voltage.
