CDBF40-HF

Overview

The CDBF40-HF is a surface-mount Schottky barrier diode manufactured by Comchip Technology. It features a single silicon junction with a maximum repetitive peak reverse voltage of 40 volts and an average forward current rating of 100 milliamperes. The device utilizes majority carrier conduction to achieve low forward voltage characteristics, making it suitable for high-efficiency rectification in compact designs.

Feature Summary

• Low forward voltage drop for improved efficiency
• Majority carrier conduction mechanism
• Designed for small surface mounting applications

Applications

• DC-DC converters
• Power supply rectification
• Polarity protection circuits

Procurement Notes

Verify the specific suffix against the manufacturer's official datasheet to confirm package type and compliance status. Ensure the ordering part number matches the required RoHS and halogen-free specifications. Cross-reference the component marking code with the mechanical data sheet to validate authenticity upon receipt.

Selection Notes

Select this component when a low-profile surface-mount Schottky diode is required for low-voltage, low-current applications. Consider the 40V reverse voltage limit and 100mA current rating during circuit design. Evaluate thermal management requirements based on the specific operating conditions and ambient temperature constraints.

Part Context

This component belongs to the CDBF series of SMD Schottky Barrier Diodes from Comchip Technology. The series is characterized by its extremely thin leadless package, designed specifically for space-constrained surface mount applications. It shares functional similarities with other low-power Schottky rectifiers in the same product family.

Replacement Considerations

Compatible substitutes include the CDBF0140R and CDBFR0145. Verify that alternative parts match the 40V reverse voltage and 100mA forward current ratings. Confirm package compatibility and electrical parameters before implementation.
