This video lecture on Zener Diode and Zener Breakdown, an extremely important topic of Semiconductor Physics, is designed for BTech 1st Year Engineering Physics students. In this lecture, we explain the construction of a Zener diode, why it is heavily doped, and how it works in reverse bias. You will learn the mechanism of Zener Breakdown, breakdown voltage, and how Zener diodes are used for voltage regulation.

You will also understand the difference between Zener Breakdown and Avalanche Breakdown, characteristics curve, and how Zener maintains constant output voltage. The lecture includes clear diagrams, simple explanation, and an exam-focused teaching approach ideal for theory and viva questions.

This lecture is useful for RGPV BTech 1st Year students and equally relevant for AKTU, VTU, GTU, JNTU, SPPU, and other universities following the same semiconductor syllabus.

📘 This Semiconductor Physics Playlist Includes:

Introduction to Semiconductors
Intrinsic & Extrinsic Types
