CZRFR11VB-HF is a single Zener diode from Microchip Technology’s Wide Bandgap Diode series. It is designed for use in applications where high voltage switching requirements present a challenge for conventional silicon technology components.

The Wide Bandgap Diode series provides an industry-leading combination of voltage ratings, current capabilities, low forward voltage drop and ESD protection, making them the ideal choice for use in many high-power applications, such as industrial systems, automotive systems and telecom systems. The CZRFR11VB-HF diode has a rated voltage of 11V, a reverse polarity voltage of 28V and a nominal current of 0.5A.

This Zener diode is specifically designed for use in high-voltage switching applications, providing a robust and efficient solution to power switching requirements. The CZRFR11VB-HF utilizes a built-in hysteresis to help maintain the device\'s breakdown voltage in the presence of voltage transients and works to protect the device from electrical over-stress. This diode features a wide operating temperature range from -55°C to 125°C, making it suitable for use in a variety of applications.

The device works by relying on a breakdown voltage which, when exceeded, causes an avalanche avalanche breakdown current that increases exponentially as the applied voltage increases. This breakdown current is regulated by the built-in hysteresis and a safe operating area (SOA) which defines the maximum current that the device can handle, ensuring the device’s safety. In addition to this, the device’s body diode has a positive temperature coefficient which increases with temperature, aiding in temperature compensation of the application.

In summary, the CZRFR11VB-HF single Zener diode is specifically designed for use in high-voltage switching applications. It provides a robust, efficient and safe solution to power switching requirements, featuring a range of impressive electrical parameters as well as a wide operating temperature range to suit many applications.
