Zener Diode: A Comprehensive Guide to Its Principles and Applications

Unlocking the Potential of Zener Diodes: A Deep Dive into Principles and Practical Applications   A Zener diode is a semiconductor device that allows current to flow forward like a regular diode but also in the reverse direction if the voltage is larger than the breakdown voltage, known as “Zener knee voltage” or “Zener voltage”. This dual-directional functionality is the defining characteristic of Zener diodes and sets them apart from other diodes. Zener diodes consist of a heavily doped P-N junction to reduce the breakdown voltage, which results in a thin depletion layer. The reduced breakdown voltage allows the diode to operate reliably in the reverse breakdown region without damaging […]
