What is a Zener diode?

A Zener Diode is a semiconductor device characterized by its ability to conduct current at a specific reverse voltage, known as the "Zener voltage," without damage. This unique property makes it ideal for applications such as voltage regulation and overvoltage protection. In forward bias, it behaves like a standard diode, while in reverse bias, it maintains a stable voltage across its terminals when the reverse voltage exceeds the Zener voltage. Zener diodes are widely used in power supply circuits to regulate voltage and in switching power supplies to generate reference voltages. Due to their compact design and simplicity, they are integral to many electronic devices. Their performance is determined by their breakdown voltage range and current capacity, allowing for flexible use tailored to specific application requirements.

Application of Zener diode

✅Voltage Stabilization in Power Supplies:
Maintains consistent output voltage despite load fluctuations.
✅Overvoltage Protection:
Safeguards circuits by limiting voltage within a safe range.
✅Reference Voltage Generation:
Provides stable reference voltages in switching power supplies.
✅Waveform Shaping:
Controls or reduces unwanted voltage components in signal circuits.
