Overview
The CDBF42-HF is a surface-mount Schottky barrier diode manufactured by Comchip Technology. It features an average forward current of 100 mA and a maximum repetitive peak reverse voltage of 40 V. The device utilizes majority carrier conduction to achieve low forward voltage characteristics, making it suitable for high-frequency applications. It is housed in a compact SOD-523F package designed for small surface mounting.
Feature Summary
- Low forward voltage drop for improved efficiency
- Majority carrier conduction mechanism
- Extremely thin and leadless package design
Applications
- Power supply rectification
- High-speed switching circuits
- DC-DC converter input/output stages
Procurement Notes
Verify the specific suffix against the manufacturer's official datasheet to confirm exact electrical tolerances and packaging specifications. Ensure the component meets required RoHS compliance standards for your target market. Cross-reference the part number with authorized distributors to confirm current availability and authenticity before procurement.
Selection Notes
Select this component when space constraints require a low-profile SMD solution with moderate current handling capabilities. The 40 V reverse voltage rating suits low-voltage DC systems. Consider the thermal performance and package size relative to the PCB layout requirements for optimal heat dissipation and mechanical stability.
Part Context
This component belongs to Comchip Technology's series of surface-mount Schottky barrier diodes. These devices are engineered for applications requiring fast switching speeds and low power loss. The product line emphasizes miniaturization while maintaining reliable semiconductor performance in compact electronic assemblies.
Replacement Considerations
Potential substitutes include the CDBF0140R or CDBFR0145-HF from the same manufacturer. Verify that alternative parts match the 100 mA forward current and 40 V reverse voltage ratings. Ensure the replacement package type is compatible with the existing footprint.
