CZRFR24VB-HF

Diodes - Zener - Single

The CZRFR24VB-HF is a single zener diode from NXP Semiconductors. This device is specifically designed for automotive, telecommunication and power management applications. It is AEC-Q101 certified and offers a wide cathode-to-anode breakdown voltage range from 12 to 33 V. It provides several features for improved flexibility, such as fast switching and low forward voltage drop, making it ideal for use in designs requiring efficient power management.

Application Field:

The CZRFR24VB-HF is designed to protect automotive systems from voltage surges. Its low forward voltage drop, high energy capability and fast switching allow it to be used in different types of automotive systems to regulate the voltage supply. It can be used in battery monitors, alternative energy controllers, lighting systems and temperature sensors, among others.

It is also suitable for telecommunications applications, such as EMC filtering, signal protection and signal conditioning. In addition, it can be used for power management in portable electronic devices, such as mobile phones, laptops and tablets.

Working Principle:

The working principle of the CZRFR24VB-HF is based on using a zener voltage breakdown mechanism. When a voltage exceeds the zener voltage breakdown level, a small current is allowed to flow through the diode instead of the protected component, thus providing protection against overvoltage.

The zener diode is made up of two segments: N-doped and P-doped. The N-doped section allows the current to flow in one direction and the P-doped section allows the current to flow in the opposite direction. When a voltage exceeding the breakdown level is applied, the electrons from the P-doped section move towards the N-doped section, thus creating a current flow from P-doped section to the N-doped section. This current is regulated by the reverse breakdown voltage and ensures that the protected component does not suffer from any overvoltage.

Conclusion:

The CZRFR24VB-HF from NXP Semiconductor is a single zener diode designed for automotive, telecommunication and power management applications. It provides fast switching and low forward voltage drop to guarantee efficient power management. The device can be used to protect automotive systems from surges, as well as EMC filtering, signal protection and signal conditioning in telecommunications applications. It works based on a zener voltage breakdown mechanism which ensures that the protected component does not suffer from any overvoltage.
