Diodes - Zener - Single

BZD27C220PWH is a type of single Zener diode designed to protect a wide range of circuits from voltage spikes. It is able to handle large voltage differences and its design ensures that it won’t be damaged by electric overloads.

Application Field

BZD27C220PWH Zener diodes are widely used in many different applications such as power supplies, voltage regulators, battery-charging circuits, and switching circuits. It is also used to protect circuits from electric overloads, prevent reverse currents, and provide noise filtering in audio applications.

Working Principle

The basic principle behind a BZD27C220PWHZener diode is that when the reverse-bias voltage across the diode is greater than the Zener voltage, current will flow freely in a reverse direction. This reverse-bias voltage is also known as the Zener voltage and it is the voltage at which the diode will start to conduct in the reverse direction.

When the reverse bias voltage becomes too large, the diode will start to conduct in the reverse direction and the Zener diode will start to clamp the excess voltage. The forward-bias voltage across the diode is limited by the Zener voltage and the excess voltage will be diverted away from the load. This ensures that the maximum voltage across the load remains within safe limits.

The BZD27C220PWHZener diode also acts as a protection device in switching circuits as it can help to limit the voltage across the load. This feature also makes it ideal for protecting sensitive electronic devices from voltage surges. In audio applications, BZD27C220PWH Zener diodes help to provide noise suppression by limiting the amplitude of audio signals.

Conclusion

The BZD27C220PWH Zener diode is a versatile and reliable single Zener diode capable of handling large voltage differences and protecting circuits from electric overloads. It is highly recommended for a wide range of applications including power supplies, voltage regulators, battery-charging circuits, and switching circuits as well as audio applications.
