Overview
The CDBM240-G is a single Schottky barrier rectifier manufactured by Comchip Technology, designed for surface-mount applications. It utilizes silicon epitaxial planar chip technology within an SOD-123F (Mini SMA) package. The device supports a maximum repetitive reverse voltage of 40 V and a continuous forward current of 2 A. Key electrical characteristics include a low forward voltage drop of 400 mV at rated current and a high surge current capability of 50 A. It operates reliably within a temperature range of -55°C to +100°C.
Feature Summary
- Ultra-high-speed switching with low forward voltage drop for improved efficiency
- Guarding against overvoltage transients in sensitive circuits
- Low profile package design optimized for board space constraints
Applications
- DC-DC converters
- Power supply rectification
- Free-wheeling diodes in inductive loads
Procurement Notes
Verify the specific suffix 'G' confirms lead-free compliance and RoHS status as per manufacturer documentation. Confirm the package designation matches SOD-123F or Mini SMA requirements for your PCB footprint. Ensure thermal management aligns with the specified junction temperature limits during operation.
Selection Notes
Select this component when a low-profile surface-mount Schottky rectifier is required for 40V applications. It is suitable where fast switching speeds and low power loss are critical. Compare thermal resistance and leakage current specifications against alternative packages if space allows for larger footprints.
Part Context
This part belongs to the CDBMH series of Schottky Barrier Rectifiers from Comchip Technology. The series emphasizes batch process design for consistent performance. These devices are engineered for low power dissipation and excellent thermal resistance compared to standard SOD-123 packages.
Replacement Considerations
Check datasheets for equivalent parts offering identical 40V/2A ratings in SOD-123 packages. Verify pinout compatibility and forward voltage characteristics to ensure circuit performance remains unchanged.
