Overview
The CDBC240SLR-HF is a Schottky barrier rectifier manufactured by Comchip Technology, designed for surface-mount applications in the DO-214AB (SMC) package. It features a maximum repetitive peak reverse voltage of 40 V and an average forward rectified current of 2 A. The device utilizes silicon epitaxial planar chip technology with metal-silicon junction construction. Key electrical characteristics include a low forward voltage drop and ultra-high-speed switching capabilities, making it suitable for high-efficiency power conversion systems.
Feature Summary
- Low forward voltage drop for enhanced efficiency
- Ultra-high-speed switching performance
- Guarding against overvoltage protection
- Lead-free construction compliant with environmental standards
Applications
- High-frequency DC-DC converters
- Power supply output rectification
- Free-wheeling diodes in inductive loads
Procurement Notes
Verify the specific suffix 'SLR' against official Comchip documentation to confirm packaging configuration and availability status. Ensure the component meets RoHS compliance requirements for your assembly process. Cross-reference the DigiKey part number 641-1732-2-nd or Mouser listings for current distribution channels. Confirm lead times directly with authorized distributors as manufacturing schedules may vary.
Selection Notes
Select this component when a 40 V reverse voltage rating and 2 A continuous current capacity are required in a compact SMC footprint. Consider its low forward voltage characteristics for improving overall system efficiency in low-voltage applications. Evaluate thermal management needs based on the DO-214AB package's power dissipation capabilities compared to smaller packages like SOD-123.
Part Context
This part belongs to Comchip's CDBC series of Super Low VF Schottky Barrier Rectifiers. The series is characterized by reduced power loss and high surge capability. The CDBC240SLR-HF specifically targets applications demanding reliable rectification in space-constrained surface-mount designs while maintaining high switching speeds and low leakage currents typical of Schottky technology.
Replacement Considerations
Check for direct substitutes within the same voltage and current ratings from other manufacturers. Verify pinout compatibility and thermal resistance values before substitution. Ensure any replacement maintains the DO-214AB package dimensions for board layout integrity.
