Diodes - Zener - Single - 3EZ22D10E3/TR12 Application Field and Working Principle

A single Zener diode is a diode specifically designed to allow large amounts of current to flow in the reverse direction when a given voltage is reached. The 3EZ22D10E3/TR12 is one such diode. This article will focus on the application field and working principle of this diode.

Application Field
The 3EZ22D10E3/TR12 is a single Zener diode with a maximum operating power of 1.2W and a low knee voltage of 10V. It has a high power tolerance, which makes it suitable for light load applications in power supplies and other equipment. This diode can be used in AC-DC and DC-DC converters, DC-AC inverters, and overvoltage protection circuits.

Working Principle
The working principle of the 3EZ22D10E3/TR12 is quite simple. When the voltage across its terminals is below the knee voltage, the diode acts as a normal diode, allowing current to flow in the forward direction. When the voltage exceeds the knee voltage of 10V, the diode begins to conduct current in the reverse direction. This makes the diode a useful tool for regulating voltage and providing protection against overvoltage spikes.

When the reverse voltage across the diode exceeds the knee voltage, the current flowing through it increases rapidly. This steadily increases the voltage across the diode until it reaches the breakdown voltage. At this point, the diode begins to act as an open switch, allowing current to flow freely in the reverse direction. Once the reverse voltage has exceeded the zener voltage, the diode will remain in the breakdown state until the voltage is reduced, and the diode returns to its normal conducting state.

The 3EZ22D10E3/TR12 is a reliable and efficient diode that can be used in a variety of applications. Its simple design and ability to regulate voltages make it a valuable tool for engineers and hobbyists alike.
