1N823AUR

Diodes - Zener - Single

The 1N823AUR is a 200mW (max) Zener diode, used to provide a well-regulated voltage source and electrically isolate it from the rest of the circuit. Instead of using a transformer to isolate the voltage, the Zener diode can provide this functionality without the need for a bulky transformer.

Application Field

The 1N823AUR is primarily used for voltage regulation, clipping, and clamping. These applications are mainly used in amplifiers, power supplies, and other power management applications to regulate or limit voltages or currents.

Working Principle

The Zener diode is a special type of diode that has a reverse breakdown voltage that is independent of temperature and current. When a Zener diode is connected to a power source with a voltage greater than the breakdown voltage, a reverse current is established and the diode will allow a constant current to flow through it. This current is independent of the voltage applied to it and thus a constant, regulated voltage is established across the diode.

In the case of the 1N823AUR, the device has a breakdown voltage of 5.6V, meaning that the regulated voltage it provides will be at or below 5.6V. The 1N823AUR also has a maximum power rating of 200mW, meaning it is suitable for applications with currents up to 400mA.

Conclusion

The 1N823AUR is a single Zener diode suitable for a variety of voltage regulation and current limiting applications. The device can be used to provide a stable, regulated voltage output, as well as to provide electrical isolation and noise suppression in electronic systems. With its wide range of applications and its low power consumption, the 1N823AUR is a reliable and versatile device.
