What Is a Zener Diode Regulator?
Zener diodes are primarily designed to regulate the output voltage of a power supply. As a voltage regulator, a stable maximum voltage is allowed to pass through the diode. This maximum voltage is determined by the voltage rating of the zener diode. Regulation of a specific voltage output ensures electronic equipment does not receive electrical power surges. These surges often destroy electronic components in computers, televisions and other electronic equipment.
