Zener diodes are a type of diode that allows current to flow in either direction but it will only operate in the forward direction when the voltage across it exceeds the breakdown voltage known as the Zener voltage. The range of Zener voltages available are typically between 1.0 to 200 volts. They are commonly used for providing an easily adjustable reference voltage for electronic circuits. In this article, we will be discussing the characteristics and applications of the UDZS4V3B RRG Zener diode as well as its working principle.

Furthermore, it is also used for signal clamping in signal conditioning and instrumentation applications. Finally, this diode is ideal for providing a memory power supply from batteries and for providing back up battery power in portable computers.

Working Principle of UDZS4V3B RRG Zener Diodes:

The UDZS4V3B RRG Zener diode is a two terminal semiconductor device which has a reverse breakdown voltage, known as the Zener voltage. In the forward bias region, the diode acts like a normal diode and allows current to pass through. When the applied voltage exceeds the Zener voltage, the diode begins to conduct in the reverse direction and this allows current to flow through the device. This flow of current is limited to a certain amount and it is known as the Zener current. The Zener current is the amount of current which the diode can handle before it is damaged.

When the reverse voltage exceeds the Zener voltage, the diode will go into avalanche breakdown and a large amount of current will flow through the device. The Zener voltage will remain fairly constant with changes in the reverse voltage or current, thus providing a constant voltage reference. This characteristic is used in many applications to provide stable voltage sources for electronic circuits.
