This article provides a brief overview of its application field and working principle in support of its usage.

Application Field

JANTX1N4493DUS is a high-reliability, low-power zener diode that has multiple advantages in consumer, industrial, and power solutions applications. Some of its potential uses include:

• Uses in the noise voltage suppression of main and redundant power and data lines
• Can be used to clamp overvoltage input circuits
• Also serves as a low-resistance voltage regulator
• Protects power lines from firing and sparking

It is designed to provide protection from voltage, current and power transients. Additionally, it offers high temperature operating range that makes it suitable for harsh environments.

Working Principle

JANTX1N4493DUS is a three terminal diode made up of materials like zinc oxide, aluminum and silicon. It operates according to the Zener voltage regulation principle, which states that when the voltage across the Anode and Cathode are above a certain limit, the Zener current flows through the device. This ensures that the voltage across the device remains constant, no matter what the input voltage.

When the operation of the diode is under its specified conditions, it operates in the breakdown region. In this region, when the voltage across is increased, the current through the diode increases exponentially up to a certain point known as the Zener breakdown voltage. Beyond this point, the current flowing through the device is kept almost constant and the voltage across the device remains fixed.

In order to effectively use the Zener diode, the Zener current must be set at the correct levels. This is done by adjusting the bias voltage applied across the device. This allows the application to take advantage of the constant voltage characteristic of the device over varying input conditions.
