GLL4748A-E3/96

Introduction

The GLL4748A-E3/96 is a two-terminal Zener diode designed for use as a voltage regulator. It offers excellent performance as a voltage regulator over a wide range of current and temperature. The device features a Zener breakdown voltage of 5.6V, and has a reverse breakdown current of 2mA. The diode has an operating junction temperature range of -65°C to 175°C.

Application Fields

The GLL4748A-E3/96 is often used in power supplies, specifically as a voltage regulator. In regulating power, the diode serves to maintain the output voltage within a preset range by sensing the current flowing through it and limiting the voltage. This ensures a stable voltage output despite fluctuations at the input side.

The diode can also be used in non-linear circuits, as noise clippers and spike suppressors. In these applications, the diode operates at a constant voltage, thereby eliminating any undesired voltage changes.

Working Principle

The GLL4748A-E3/96 operates on the principle of the Zener effect, in which the diode’s reverse-biased voltage is limited by its PN junction. The diode works by regulating the current through the PN junction in both directions.

When a reverse voltage is applied to the diode, the electric field around the junction increases until it reaches a level where the charge carriers across the junction start to conduct in the reverse direction. This reverse current, known as the Zener current, will continue to flow until the forward voltage drop of the diode is reached. The voltage at which the Zener current starts to flow is known as the Zener voltage.

The GLL4748A diode has a Zener voltage of 5.6V, and a reverse breakdown current of 2mA. This means that the diode can safely handle 2 mA of current without the voltage at the junction exceeding 5.6V. The diode can be used to safely regulate a wide range of currents and temperatures.

Conclusion

The GLL4748A-E3/96 is a single Zener diode designed for use as a voltage regulator in power supplies and other electronic circuits. The diode operates based on the Zener effect, in which the reverse-biased voltage is limited to the diode’s PN junction. The diode has a Zener voltage of 5.6V, and a reverse breakdown current of 2mA. The diode offers excellent performance as a voltage regulator over a wide range of current and temperature.
