Diodes – Zener – Single

The ACZRM5242B-HF is a single Zener diode from RS Components that provides an extremely efficient form of voltage regulation. This component is able to ensure an output voltage that is resilient to shocks, temperature changes and other sudden external influences. It also has the ability to operate reliably over a wide range of input and output frequencies and voltage levels.

The ACZRM5242B-HF is a valued component for application in voltage regulators and in applications that require a wide temperature range for operating. It is also suitable for use in industrial control electronics, communications and many other applications that demand high reliability and a wide temperature range.

Product Overview

The ACZRM5242B-HF is an integrated Zener diode that provides voltage regulation over a wide temperature range and is able to withstand maximum junction temperatures of up to 150°C. It has a maximum power dissipation of up to 2.5W and is constructed with an epitaxial layer, which makes it capable of efficient current rectification.

It offers excellent stability and has an ideality factor of 50. This feature also makes it highly tolerant against voltage changes and helps to keep the output voltage level close to the value specified in the datasheet.

Features and Benefits

The ACZRM5242B-HF provides several benefits for users in different applications. The first benefit is that the device offers a high degree of stability for voltage regulation and is quite efficient in rectifying current. It also allows for excellent temperature compensation and can be used in wide temperature-range environments. Furthermore, the epitaxial construction allows for better figure of merit and faster turn-on times.

The product is RoHS compliant and its comparatively small size makes it an ideal choice for applications that demand a space-saving component. This small size also allows manufacturers to save on costs since the component’s production and packaging costs are considerably lower than those of larger components.

Working Principle

The ACZRM5242B-HF is a Zener diode, which has three main components: the cathode, anode, and Zener region. When the device is not conducting, it operates as a regular diode, with a valence band of electrons filling the gap between the anode and cathode regions. When a certain voltage is applied to the device, it begins to conduct and electrons start to flow through the Zener region.

The Zener region consists of a high-resistance semiconductor layer, which acts as a resistor, reducing the maximum current that is able to pass through the diode. This is known as the Zener effect and it prevents the diode from shorting out or destroying its associated electronic components. As the input voltage increases, the current through the Zener region increases and the output voltage remains stable. This ensures that the output voltage remains consistent and unaffected by temperature or external interference.

Conclusion

The ACZRM5242B-HF is a small, integrated Zener diode that provides excellent voltage regulation over a wide range of temperatures. Its epitaxial layer construction allows for better figure of merit and improved turn-on time while also providing good temperature compensation characteristics. Furthermore, the product is RoHS compliant and its low cost and small size make it an ideal choice for different applications.
