Reverse breakdown voltage, v(br)r : Typical values are around 0.25 to 1ma for a 1 watt zener diode.

There Are Available Some Standard Values Of Reverse Breakdown Voltage Zener Diodes.

This limiting voltage is called the zener voltage' or breakdown voltage and the resulting large current as 'zener current When the forward voltage across the diode equals 0v, forward current (if) equals 0 ma. Its default value is 1.0 and typical value is 1.1.

Reverse Leakage Current, Ir :

Breakdown voltage is an inherent property of a diode. A zener diode is a normal diode designed with a specific breakdown voltage. A typical value for the breakdown voltage is for instance 6.2v.

At If = 1.0 Ma If=15Ma :

Knee current (i zk) there is a minimum current required to keep the diode in breakdown for voltage regulation. Zener diodes can also withstand higher reverse current flow than comparable pn diodes, and are available with various power ratings, typically from 500mw to. 2.1.1 are typically used in applications such as power supplies using both high voltage and high current, where they rectify the incoming mains (line) voltage and must pass all of the current required by whatever circuit they are supplying, which could be several amperes or tens of amperes.

It Should Be Noted That The Rms Value For Any Voltage Will Be 1/√2 Times The Constant Value.

Rectifier diodes, like those shown in figure. Here, the breakdown voltage is known as avalanche breakdown voltage. The resistor value is chosen to limit the current that flows through the diode.

The Device Is Named After Clarence Zener Who Discovered This.

A typical value of reverse breakdown voltage in a diode is a)0.7 v. Max forward continuous current, ifm : This effectively limits the voltage across the diode.
