Working Principle

Working Principle of the 1N823UR-1 Diode is similar to most Zener Diodes. It works using the inverse breakdown effect. When the reverse bias reaches to the breakdown voltage, the diode gets forward-biased and then a sharp voltage drop across the diode occurs.

When current passes through the diode in the forward bias, the depletion layer formed by the depletion layer formed by the application of reverse bias becomes a thin layer. This ensures a very low voltage drop across the diode. As a result, the Zener Voltage is stabilized.

The 1N823UR-1 Zener diode also works as an over-current protection device. The voltage breakdown affects the current-to-voltage ratio, thus limiting the voltage across the diode. This helps to keep large current surges from damaging electrical equipment.
