A Zener diode is a special type of diode that is designed to conduct current in the reverse direction once a certain reverse voltage, called the Zener voltage (or breakdown voltage) is reached. This device, known as GLL4763A-E3/97, is a 3.0 Volt, 500 mW Zener diode designed for use in a variety of applications. This article will examine the application field and working principle of the GLL4763A-E3/97 to better understand its use.

Application Field

GLL4763A-E3/97 is used in a wide range of applications. The most common use is as a voltage reference and as a shunt regulator in power supplies, DC converters, switch-mode power supplies, and low-voltage DC-DC converters. It is also used in voltage regulators and clamping circuits. It can also be used to control the voltage in rectifiers, overvoltage suppression, surge protection, and to regulate transients. It is a popular choice for commercial and consumer electronics applications due to its low reverse leakage current and its ability to operate at high temperatures.

Working Principle

A Zener diode conducts current when a reverse voltage is applied. When the voltage exceeds the breakdown voltage (Zener voltage) of the diode, it begins to conduct. The diode is designed to have a very low threshold voltage and an extremely linear current-voltage characteristic, which makes it well suited for use as a voltage reference. As a voltage reference, the diode allows a current to flow when the voltage reaches a certain level, maintaining a stable voltage across the diode regardless of changes in the current. As a shunt regulator, the diode limits the voltage passing through the circuit by passing excess current off to ground. The diode is able to maintain a very stable voltage even as the current changes, thus providing excellent regulation.

Conclusion

The GLL4763A-E3/97 is a 3.0 Volt, 500 mW Zener diode designed for use in a variety of applications. It is an ideal choice for a variety of commercial and consumer electronics applications due to its low reverse leakage current and its ability to operate at high temperatures. As a voltage reference or shunt regulator, the diode can provide very stable voltage control even when the current changes, making it an ideal choice for power supplies, DC converters, switch-mode power supplies, low-voltage DC-DC converters, voltage regulators, clamping circuits, rectifiers, overvoltage suppression, surge protection, and transient regulation.
