Diodes are a class of electrical components whose primary job is to actively manage the flow of electrons between two points in circuits. A Zener diode is a type of a diode whose job is to regulate the voltage across two points by allowing only a certain amount of current to pass through it. GLL4754-E3/96 are zener diodes and are typically used in parts of a circuit where a specific, and consistent, voltage is required.

Physical Characteristics

The GLL4754-96 is a 4mm x 4mm square chip. It has a maximum height of 1.6mm and a minimum height of 1.4mm, meaning it does not have a large profile, making it very suitable for use in space-limited circuits. It has a maximum operating temperature of 150℃, and can be stored at temperatures up to 177℃.

Electrical Characteristics

Each GLL4754-E3/96 is a single zener diode with a 5.6V voltage rating, meaning that it works by allowing electrons to pass through it until the voltage across its leads reaches 5.6V. It has a maximum power dissipation rating of 1W, meaning that no more than 1 Watt of power should be dissipated through the diode for it to operate correctly. As for its major electrical characteristics, the GLL4754-E3/96 has a Zener resistance rating measured at 8 Ohms and a maximum forward current rating measured at 88mA. Both of these are important in order to be able to accurately calculate power dissipation.

Application Fields and Working Principles

One of the most common usages of GLL4754-E3/96 zener diodes is to protect other electrical components and circuits from over-voltage or high-frequency interference. This is done by connecting the zener diode in parallel to the two points of the circuit. When a voltage spike, or an excessive current, flows across the circuit, the zener diode is activated, allowing only a certain amount of current to pass through it until the voltage is regulated back to an acceptable level. Due to this, this type of zener diode is ideal in circuits with components such as transistors and other delicate electronic parts, such as chips, integrated circuits and so on.

Another application of the GLL4754-E3/96 is in converters and rectifiers. In this situation the diodes are used to convert alternating current (AC) to direct current (DC). This is usually done by connecting the diode in series with the circuit which needs to regulate the voltage. When an AC source is applied to the circuit, the diode allows only a certain amount current to pass through it, creating a smoother DC output.

These are just two of the applications in which GLL4754-E3/96 zener diodes can be used. They can also be used in voltage-level-shifting circuits, as well as in current-limiting circuits. In fact, they are even used in some handheld gadgets such as mobile phones and DSMs, thanks to their small form factor.
