Zener Diode And Its Applications

March 01, 2021 Post a Comment

Zener diode applications zener diodes are used for voltage regulation as reference elements surge suppressors and in switching applications and clipper circuits. Diodes can be classified into different types by its operational mechanism.

Main Difference Between Pn Junction Diode And Zener Diode

The zener diode operates just like the normal diode when in the forward bias mode and has a turn on voltage of between 03 and 07 v.

Zener Diode And Its Applications. Applications of zener diode. For an amplifier stage or as a voltage stabilizer for low current applications. Among numerous uses let us discuss some crucial applications of zener diode.

In these diodes the range of forward resistance is in ohms and the reverse blocking resistance is in mega ohms. In power supplies and many other circuits zener diode finds its application as a constant voltage provider or a voltage reference. However when connected in the reverse mode which is usual in most of its applications a small leakage current may flow.

Different diodes used as switching elements are the zener diode tunnel diode varactor diode schottky diode power diodes etc. Regulating the voltage of a circuit is its ability to keep the output voltage fixed regardless of the variation in input voltage or load current. Working of zener diode zener diode operation.

The main applications of these diodes are in battery charging devices like inverters. Another mechanism that produces a similar effect is the avalanche effect as in the avalanche diode. Applications of zener diodes zener diodes finds a wide applications commercially and industrially.

Some of the important applications of a zener diodes are as a voltage regulator or stabilizer as a meter protector and as a wave shaper. The binary decision trees in computing are based on logic gates enabled by diodes that control whether a switch is on 1 or off 0. They are discussed below in detail.

Thus they are designed in various ways for specific applications. In the previous article we have discussed diodes. The zener diode is therefore ideal for applications such as the generation of a reference voltage eg.

Symbol of zener diode. The only conditions are that the input voltage should be greater than zener voltage and the series resistor should have a minimum value such that the maximum current flows through the device. Although hundreds of millions of diodes appear in modern processors theyre functionally the same as the diodes you buy at the electronics storejust much smaller.

Zener diode is a specially doped special typer of diodes used in various applications in electronics circuits mainly it provides stable voltage output across the circuit terminals across which the zener diode is connected. Since it has high current and voltage performance these can be used in electrical devices which are used to suppress high peak voltages.
