Introduction

The 3EZ15D10/TR12 is a single Zener diode from STMicroelectronics. It is a 2-lead Zener diode constructed with Pb free terminals that also features a guard ring for maximum protection. The 3EZ15D10/TR12 is suitable for all kinds of general purpose applications as well as industrial applications. It has a very low voltage, making it a suitable choice for low-voltage applications.

Application Field

The most common application of the 3EZ15D10/TR12 is in voltage regulation. It is often used in power supply designs to protect components from overvoltage. The low voltage of this Zener diode helps prevent circuits from being damaged by overvoltage, as the Zener diode will effectively absorb the excess voltage.The 3EZ15D10/TR12 can also be used to protect circuits from reverse polarity. By properly setting the Zener diode across the power lines, it can act as a reverse polarity protection, allowing the current to flow correctly and preventing component damage.Furthermore, the 3EZ15D10/TR12 can also be used for noise suppression, as it can suppress the noise generated by rapid changes in current. This can be especially useful in radio frequency applications, where it can prevent unwanted signals from interfering with the radio signal.

Working Principle

The 3EZ15D10/TR12 works by using an effective breakdown voltage, which is the voltage at which the current can flow through the diode without any restriction. When the voltage reaches a certain level, the diode begins to break down, allowing the current to flow freely. This breakdown voltage is usually a very low voltage, typically less than 5 volts.In addition, the 3EZ15D10/TR12 is designed with a guard ring. This helps protect the diode against external electric fields, which can cause damage to the diode if it cannot handle the excess voltage or current.The 3EZ15D10/TR12 is a very useful component for low-voltage applications, as it can protect from overvoltage, reverse polarity and radio frequency interference. It is a simple device that is easy to integrate into most circuits, and its low voltage makes it an ideal choice for low-voltage systems.
