Unit V: The P-N Junction Diode | BCA 2nd Semester Fundamentals of Electrical and Electronics Notes Pdf

A PN Junction Diode is one of the most basic semiconductor devices available, with the property of only flowing current in one direction. However, unlike a resistor, a diode does not act linearly with respect to applied voltage since it has an exponential current-voltage ( I-V ) connection, thus we can't just use an equation like Ohm's law to describe its operation.

As the width of the depletion layer around the PN junction shrinks, an appropriate positive voltage (forward bias) supplied between the two ends of the PN junction can supply free electrons and holes with the extra energy they need to pass the junction.

In this “The P-N Junction Diode – Fundamentals of Electrical and Electronics” you will learn about the following topics:

1. Formation of a Space-Charge Region in a P-N Junction
2. Energy Band Structure and Barrier Potential
3. The P-N Junction under Forwarding Bias and Reverse Bias
4. Characteristic Curve
5. Diode Load Line
6. Application of Diode
7. Logic Gates: AND, OR, NOT
8. Rectifiers: Half and Full Wave
9. Zener Diode
10. Characteristics of Zener Diode
11. Applications of Zener Diode
