CDBC540-G Description

Short technical summary and product information.

The CDBC540-G is a Schottky rectifier diode manufactured by Comchip Technology, designed for high-efficiency power rectification applications. It is rated for a maximum reverse voltage of 40V and an average rectified forward current of 5A, with a typical forward voltage drop of 550mV at 5A. The device offers fast recovery characteristics, with recovery times of 500ns or less at currents above 200mA, making it suitable for high-frequency switching circuits.

 

This diode is housed in a standard DO-214AB (SMC) surface-mount package, which provides a compact footprint for automated assembly processes. The operating temperature range spans from -40°C to 125°C, allowing reliable performance in a wide variety of environmental conditions. The part is RoHS3 compliant and REACH unaffected, ensuring compatibility with current environmental regulations.

 

Typical applications include polarity protection, freewheeling diodes, and DC-DC converter output rectification in power supply designs. The low forward voltage drop minimizes power dissipation, improving overall system efficiency in battery-powered and low-voltage circuits.
