Introduction

3EZ22D10/TR8 is a single element diode in a SOT–23L or SC–70 package, which is often used for low-power and compact design applications. It provides an optimal balance between size and reliability with low forward voltage drop and minimum leakage current. The device has a low profile package and operates from −40 °C to +125 °C and is available on tape and reel.

Application Field

With its low profile package and excellent operating temperature, 3EZ22D10/TR8 is well-suited for applications in consumer electronics, industrial and telecommunications. It is mainly used in portable equipment, such as LCD panels and LAN cards, or any other application that requires a tightly regulated voltage drop.3EZ22D10/TR8 is suitable for applications where the output of the regulator is connected to the power supply of a load, such as a television or computer monitor. It can be used to protect the load against inrush current, while still providing a tightly regulated voltage drop. It is also excellent for providing tight regulation in switching power supplies.

Working Principle

3EZ22D10/TR8 is a Zener diode that works by exploiting the flow of electrons across a junction. When a voltage is applied across it, the depletion region increases and decreases with voltage, creating a depletion region around the junction. This depletion region limits the current flow across the junction, as well as the associated voltage drop.At forward bias, the diode works by allowing electrons to flow in the forward direction, and at the same time, it dampens the flow of current in the reverse direction. This means when the diode is connected in series with the load, it can help to regulate the current and voltage going through it, while still providing tight regulation.

Conclusion

3EZ22D10/TR8 is an ideal single element diode for low-power and compact design applications. It provides an optimal balance between size and reliability, with low forward voltage drop and minimum leakage current. It is well-suited for applications such as consumer electronics, industrial and telecommunications, providing tight regulation for switching power supplies and protecting loads against inrush current. It works by exploiting the flow of electrons across a junction and limiting the current flow across it.
