Zener Voltage Pass Regulator Explained with Example

July 4, 2022November 1, 2019 by Michal

A Zener Diode is a special purpose diode used for voltage regulation in reverse bias. Zener diode work under breakdown region for typical operation. A minimum current of Zener knee current must be maintained to keep the voltage regulated.

Derivation of Diode Current Equation, Calculator, and Example

February 11, 2024September 4, 2019 by Michal

The diode current equation depends on the dark saturation current, the charge of an electron, and external voltage. We also provide a calculator for the diode current equation.

3 Methods of testing a diode with multimeter and oscilloscope

July 4, 2022August 15, 2019 by Michal

Testing a diode with a digital multimeter in two ways, diode testing portion, and ohmmeter. A diode test is considered passed if it shows low resistance/voltage drop on forward bias and high resistance/voltage drop in reverse bias. A diode curve tracer uses an oscilloscope for VI characteristics graph.
