Zener Diode , not only allow the flow of current when used in forward bias, but they also allow the flow of current when used in the reversed bias so far the applied voltage is above the breakdown voltage known as the Zener Breakdown Voltage. Or in other words Breakdown voltage is the voltage, on which Zener Diode starts conducting in reverse direction. Also it maintains a constant output voltage in the breakdown region, even though the current through
it varies. This is an important feature of the zener diode, which can be used in voltage regulator applications. Therefore a zener diode is sometimes called a Voltage-regulator diode. JSCJ offers Tight Tolerance Zener Diodes, as tight as 3%, in voltages ranging from 3V to 39V, includes SMA , SMB ,
SOD-123, 323,523,723 ,SOT-23,323,363,523 packages .

Advantages of zener diode:

● The size of the Zener diode is so small that it can be used in smaller circuits and also in cell phones.

● Zener diodes are less expensive when compared to other diodes.

● Zener diodes can be used for controlling, regulating, and stabilizing the voltage in the circuit.

● These diodes have a very high-performance standard.

● The compatibility of the Zener diodes is good that they are used in regulating voltage.

Applications of zener diode:

● It is normally used as voltage reference

● It is used in voltage stabilizers or shunt regulators.

● It is used in switching operations

● It is used in clipping and clamping circuits.

● It is used in various protection circuits
