Overview
The CDBFR40 is a Schottky Barrier Diode manufactured by Comchip Technology, designed for surface-mount applications. It features a 40V repetitive reverse voltage rating and a 200mA average forward current capability. The device utilizes a compact DFN (1005) package to optimize board space. Key electrical characteristics include a low forward voltage drop and high surge current handling, making it suitable for efficient power conversion and signal rectification in low-profile electronic circuits.
Feature Summary
- Schottky barrier technology for ultra-high-speed switching
- Low profile surface mount design for board space optimization
- High efficiency with low forward voltage drop
- Guarding against overvoltage conditions
Applications
- Low voltage DC-DC converters
- Power supply rectification
- Signal detection circuits
- Overvoltage protection modules
Procurement Notes
Verify the specific suffix and tape-and-reel specifications when ordering. Confirm RoHS compliance status and lead times directly with authorized distributors. Ensure the procurement channel provides valid traceability documentation for quality assurance purposes.
Selection Notes
Select this component for designs requiring a balance between small footprint and moderate current handling at 40V. Consider the thermal resistance of the DFN package for heat dissipation requirements. Evaluate the forward voltage characteristics against system efficiency targets compared to standard PN junction diodes.
Part Context
This part belongs to the Comchip Technology CDBF series of surface-mount Schottky diodes. The series emphasizes batch process design for consistent performance. It serves as a compact alternative to larger through-hole rectifiers in modern consumer and industrial electronics.
Replacement Considerations
Check for direct pin-compatible substitutes within the same voltage and current ratings. Verify that any replacement maintains the same DFN package dimensions and thermal characteristics to ensure mechanical fit.
