3.9V 0.5watt 1N4730A Zener diode ±5% voltage tolerance pack of 50pcs

A zener diode is a semiconductor device that protects circuits from overvoltage. Zener diodes have a voltage drop that increases with applied voltage. Zener diodes are used in voltage regulation, as reference elements, surge suppressors, switching applications, and clipper circuits. When the diode is conducting, the series resistor limits the current through the diode and drops the excess voltage. When forward-biased, a zener diode behaves just like any other diode. When connected in reverse-biased mode, a small leakage current flows through the diode. As the reverse voltage approaches the predetermined breakdown voltage, current begins to flow through the diode. Zener diodes are semiconductor diodes used to regulate the voltage across them to a level that is safe for electronic circuits. The diode can be used to block a high-voltage power supply as well as provide a regulated voltage source to power circuits.
