Product Code : 800px-Zener
Brand Name : Max G Tech
Product Description

A Zener diode is a diode which allows current to flow in the forward direction in the same manner as an ideal diode, but also permits it to flow in the reverse direction when the voltage is above a certain value known as the breakdown boltage, "Zener knee voltage", "Zener voltage", "avalanche point", or "peak inverse voltage".

The device was named after clarence zener, who discovered this electrical property. Strictly speaking, a Zener diode is one in which the reverse breakdown is due to electron quantum tunnelling under high electric field strength—the zener effec. However, many diodes described as "Zener" diodes rely instead on avalanche breakdown as the mechanism. Both types are used with the Zener effect predominating under 5.6 V and avalanche breakdown above. Common applications include providing a reference voltage for voltage regulator, or to protect other semiconductor devices from momentary voltage pulses.
