When this applied reverse bias voltage is increased gradually at a certain point a rapid increase in the reverse current can be observed.

Diode reverse breakdown voltage definition. The corresponding applied reverse voltage at this point is known as breakdown voltage of the pn junction diode. This is also known as reverse breakdown voltage. The corresponding applied voltage is referred to as the breakdown voltage.

Do not be confused into thinking that this breakdown means that the diode has been damaged. The amount of reverse bias that will cause a p n junction diode to break down and conduct in the reverse direction. As with forward voltage a current will flow if the connected voltage exceeds this value.

The breakdown voltage of a zener diode is carefully set by controlling the doping level during manufacture. The maximum reverse bias voltage that can be applied to a p n diode is limited by breakdown. The breakdown voltage is a key parameter of power devices.

The diode is heated so greatly that subjecting it to a voltage greater than the breakdown voltage damages it irrevocably. The result is an avalanche breakdown a sudden and astounding increase in current. The reverse voltage is the voltage drop across the diode if the voltage at the cathode is more positive than the voltage at the anode if you connect to the cathode.

Exceeding the breakdown voltage of a diode per se is not destructive. Breakdown voltage is a parameter of a diode that defines the largest reverse voltage that can be applied without causing an exponential increase in the leakage current in the diode. The diode can no longer bear the pressure and the floodgates are forced open.

Breakdown is characterized by the rapid increase of the current under reverse bias. The voltage at which some specified and significant conduction occurs this appnote explains. This is usually much higher than the forward voltage.

The voltage below which no significant conduction occurs breakdown voltage. Although exceeding its current capacity will be. The name zener diode was named after the american physicist clarance melvin zener who discovered the zener effect.

Maximum reverse standoff voltage. A zener diode is a p n junction semiconductor device designed to operate in the reverse breakdown region.
