Schematic Diagram of a P-N Junction Diode: The diagram illustrates the basic structure of a p-n junction diode with p-type silicon on one side, n-type silicon on the other, and the anode and cathode ...

Duraton: 4 hours. In this module on pn junction under bias, we will cover the following topics: Energy band diagram of pn junction under bias, Capacitance-voltage characteristics, Impact ionization, ...

The PN junction is one of the primary building blocks of semiconductors. Diodes and Thyristors A diode (one way valve) is a PN junction with p-type on one side and n-type on the other.

In forward mode, approximately 150 µA flows through the diode, causing D4 to be reverse-biased and holding comparator U1’s inverting input low. This turns off the red LED.

The required PIV rating could be resolved by initially substituting a test diode with a high voltage rating, and scoping later. This left only the unknown junction capacitance, Cj, and reverse ...
