Zener Diode Power Calculator
A Zener Diode Power Calculator is used to calculate the maximum power that the diode can safely dissipate. Zener diodes are semiconductor devices that primarily operate in the reverse-bias mode. They are designed to maintain a constant voltage across their terminals, called the Zener voltage even when the current through the diode varies within a certain range. Zener Diodes are used for voltage regulation in power supplies, voltage clamping, overvoltage protection, and voltage reference circuits and are available in various voltage ratings and power ratings to suit various requirements.

A Zener diode maintains a nearly constant voltage known as the zener voltage (Vz) across its terminals even when the applied voltage exceeds this value. It is designed to exhibit a controlled breakdown when the reverse bias breakdown voltage is exceeded. This is achieved due to the specific doping profile of the diode, which results in a sharp breakdown voltage characteristic. This feature makes it well-suited for applications such as the generation of a reference voltage and as a voltage regulator.
Example: If a Zener Diode has a voltage of 6 V and a maximum current rating of 1.5 A, what is the maximum power that can flow through the diode?
