Working Principle

The CZRUR12VB-HF is a PNP Zener-diode single, utilizing a high-temperature Zener structure on a high power-rated device. The diode regulates the current through the device based on temperature, voltage, and other factors. Under steady-state conditions, the diode will block any current from passing through it. However, when the current exceeds a certain voltage threshold, known as the Zener voltage, the diode moves into the Zener region and permits current to flow through the device. This is known as Zener-breakdown.

The breakdown voltage for the diode is fixed, and is usually quite precise. The CZRUR12VB-HF has a wide range of breakdown voltages, with peak current ratings up to 12 volts. The higher the Zener voltage, the higher the voltage that can be allowed to pass through the device safely. The device also offers excellent efficiency and reliable operation over a wide range of temperatures.

The device is designed to be used in a variety of power supplies, providing accurate and efficient voltage control. Additionally, the device can also be used as a component protection diode to protect other components from power surges, and in AC line regulators to regulate current levels. The CZRUR12VB-HF can be used in high-frequency switching applications, making it a versatile device for a variety of applications.
