Diodes - Zener - Single: JANTX1N4961 Application Field and Working Principle

Introduction

The JANTX1N4961 single zener diode is a high quality and low voltage device. It is designed to supply a controllable resistance over a wide range of voltages and current levels. Its application field and working principle shall be discussed in this article.

Applications

The JANTX1N4961 Zener Diode has a wide range of applications. Owing to its relatively low voltage and series resistance, it is an ideal device for use in precision power-supply regulation, voltage-clamping, and voltage-regulator circuits. Its low series resistance and low reverse-voltage noise make it useful for protection circuits where reliability, accuracy, and low noise are important. Its low temperature and package size makes it suitable for many other electronics application.

Working Principle

The JANTX1N4961 Zener diode operates in the same manner as a conventional diode, however the construction of a zener diode permits current to flow in the reverse direction. This current can be controlled, regulated, and manipulated to modify the output of a circuit. The body of the diode exhibits a breakdown voltage, determined by the doping of the body and the doping of the semiconductor, and the current through the diode is then determined by the voltage across it. The Zener diode can be modified to produce a \'clamping\' or \'shunt\' configuration. In this circuit, the breakdown voltage of the diode is set determined by the load current. This current is maintained at a constant level resulting in the maintaining of a constant output voltage.

Conclusion

In conclusion, the JANTX1N4961 Zener diode is a device with a wide range of uses. Its low voltage and series resistance make it ideal for a range of voltage sensitive circuits, and its low noise and temperature performance means that it is reliable in many applications. While the basic principle is the same for all zener diodes, the JANTX1N4961 is designed for a specific application and therefore should be used with the correct parameters for operation.
