Introduction

3EZ27DE3/TR12 is a single Zener diode. It creates a small controlled reverse voltage across an electronic component in order to regulate the component\'s power dissipation. This component finds its application field in the manufacture of high-voltage diodes and switches, voltage-sensitive relays, and LEDs. This component is also used in the voltage regulation of AC/DC systems, oscillators, amplifiers, and flying capacitors.

Construction

The 3EZ27DE3/TR12 is a single Zener diode. It consists of a semiconductor junction within a hermetically sealed case. This component consists of an anode, a cathode, and a reverse-biased semiconductor junction. This junction is referred to as the “Zener” junction and it forms the heart of this component. The 3EZ27DE3/TR12 is designed to operate in both forward (normal) and reverse (Zener) directions.

Application Field

The 3EZ27DE3/TR12 component finds its application field in the manufacture of high-voltage diodes and switches, voltage-sensitive relays, and LEDs. It is also used in the voltage regulation of AC/DC systems, oscillators, amplifiers, and flying capacitors. Furthermore, this component is used in high-voltage power supplies, television sets, automotive electronics, telecommunications networks, and other applications.

Working Principle

The 3EZ27DE3/TR12 component operates on the principle of reverse-bias breakdown. When the reverse voltage across the component exceeds a certain threshold, the non-conductive medium of the junction is disturbed and electrons start to flow from the cathode to the anode. This effect is known as the Zener effect and is the most important feature of this component. The breakdown voltage of the 3EZ27DE3/TR12 component is designed to be precisely controlled in order to allow the component to precisely regulate the voltage of the connected node.
