Overview
The CDBMS540LR-HF is a Schottky barrier rectifier manufactured by Comchip Technology. It features a maximum repetitive reverse voltage (VRRM) of 40 V and an average forward current (IF) of 5 A. The device utilizes a low-profile SOD-123FL package, which is thinner than standard SOD-123 variants. Key electrical parameters include a maximum forward voltage drop (VF) of 0.55 V at 5 A and a peak forward surge current (IFSM) of 110 A. The component operates within a junction temperature range of -55°C to +150°C.
Feature Summary
- Low profile package design for space-constrained applications
- High efficiency with low forward voltage drop
- Ultra-high-speed switching capability
- Guarding against overvoltage conditions
Applications
- Power supply circuits
- DC-DC converters
- Free-wheeling diodes in inductive loads
- Polarity protection circuits
Procurement Notes
Verify the specific suffix 'LR' corresponds to the low-profile SOD-123FL package variant when sourcing. Confirm RoHS compliance status as manufacturing transitions may affect certification documentation. Ensure the ordering part number matches the exact voltage and current ratings required for the target circuit design to avoid compatibility issues.
Selection Notes
Select this component for designs requiring high current handling in compact footprints. The low forward voltage minimizes power loss compared to standard silicon rectifiers. Consider the thermal resistance characteristics of the low-profile package for heat dissipation requirements. Verify that the 40 V reverse voltage rating provides sufficient margin for the application's peak inverse voltage.
Part Context
This component belongs to Comchip Technology's CDBMS series of Schottky barrier rectifiers. The series is characterized by silicon epitaxial planar chips and metal-silicon junctions. These devices are designed to offer superior performance in terms of reverse leakage current and thermal resistance compared to conventional rectifiers.
Replacement Considerations
Direct substitutes must match the 40 V / 5 A rating and SOD-123FL package. Check manufacturer datasheets for equivalent parts from other vendors ensuring identical pinout and electrical specifications.
