CDBFR0540 Description

Short technical summary and product information.

The CDBFR0540-HF from Comchip Technology is a surface-mount Schottky barrier diode designed for efficient rectification in low-voltage, high-frequency applications. It is rated for a repetitive peak reverse voltage of 40V and an average forward rectified current of 500mA.

 

Key electrical characteristics include a low forward voltage of 640mV maximum at 1A (25°C) and 510mV typical at 0.5A, ensuring minimal power loss. The diode offers a fast reverse recovery time of 22ns, making it suitable for switching power supplies and DC-DC converters. Reverse leakage current is 10µA maximum at 40V (25°C), and junction capacitance is 170pF at 0V.

 

The device is housed in a compact 1005 (2512 Metric) / SOD-323F package, which is extremely thin and leadless, ideal for space-constrained designs. It supports surface-mount assembly and is RoHS3 compliant, REACH unaffected, and halogen free. Operating junction temperature range is -40°C to +125°C.
