Overview
The CDBC540-G is a surface-mount Schottky barrier rectifier manufactured by Comchip Technology. It features a DO-214AB (SMC) package and supports a maximum repetitive peak reverse voltage of 40 V with an average forward rectified current of 5 A. The device utilizes silicon epitaxial planar chips for high efficiency and low power loss. It is designed for applications requiring fast switching and low forward voltage drop, operating within a junction temperature range of -55°C to +175°C.
Feature Summary
- Schottky barrier construction for low forward voltage drop and minimal power loss
- Silicon epitaxial planar chip design ensuring high reliability
- Suitable for surface mount applications in compact circuits
Applications
- Low voltage, high frequency inverters
- Free wheeling diode circuits
- Polarity protection systems
Procurement Notes
Verify the specific suffix and marking codes against official Comchip Technology documentation to ensure authenticity. Confirm that the component meets required RoHS compliance standards for your assembly process. Cross-reference the manufacturer part number with authorized distributor catalogs to validate sourcing channels and avoid counterfeit components.
Selection Notes
Select this component when a 5 A current rating and 40 V reverse voltage are required in a surface-mount form factor. Consider the DO-214AB package dimensions for PCB layout constraints. Evaluate thermal management requirements based on the specified junction temperature limits and forward voltage characteristics under load conditions.
Part Context
This component belongs to the Comchip Technology SMD Schottky Barrier Rectifiers series. It shares the same physical package and general technology as other variants in the family, such as the CDBC520-HF, but differs in its specific voltage rating. The series is characterized by low dropout voltage and suitability for high-frequency switching applications.
Replacement Considerations
Direct substitutes include the CDBC520-HF for lower voltage applications or the CDBC100-G for higher voltage requirements. Ensure any replacement maintains the DO-214AB footprint and matches the 5 A current handling capability.
