VLZ7V5C-GS18

Diodes - Zener - Single

The VLZ7V5C-GS18 is a single Zener diode. It is a type of diode that is specifically used for voltage regulation and limiting. Zener diodes have some unique properties, making them ideal for applications that require precisely specified voltage levels, such as voltage stabilization and surge protection.

The VLZ7V5C-GS18 is primarily used for Voltage Regulation and limiting applications. It provides a fixed breakdown voltage of 7V, with a 5% temperature coefficient. At high current levels, the diode is designed to withstand a power dissipation of 500mW. The diode has a maximum reverse leakage current of around 1uA. It is rated at a junction temperature of 125°C and has a packaging style of Safety and Emissions in accordance with the RoHS Directive.

The working principle of a Zener diode is based on the principle of Avalanche breakdown. In this phenomenon, electrons flowing in a diode are accelerated and attain a velocity higher than that of a threshold value, leading to a large current flow in the diode. This causes an electric field in the layer of the diode to become so large that it “breaks down” and allows current to flow in both directions across the junction.

When operated in reverse bias mode, this breakdown voltage is very narrowly defined, allowing it to be tailored precisely to a specified voltage level. In the case of the VLZ7V5C-GS18, this voltage level is 7V and is suitable for stabilizing and limiting the output of various power supplies and circuits.

In addition to its voltage regulation and limiting applications, the VLZ7V5C-GS18 can be used for the protection of electronic components from power surges and spikes. Its fixed breakdown voltage makes it ideal for this purpose as it allows for the safe passage of excess charge through the diode when a power spike is detected. In fact, Zener diodes are used as stand-alone surge protection devices in many electronic circuits.

VLZ7V5C-GS18 is a high-performance, rugged Zener diode that offers reliable performance in Voltage Regulation and Limiting applications, as well as Surge Protection. With a precisely specified breakdown voltage, it is ideal for a wide range of applications, from power supply regulation to power spike protection.
