Overview
The CDBER0140L is a Schottky barrier diode manufactured by Comchip Technology, designed for surface mount applications. It features a 40V repetitive reverse voltage rating and a 100mA forward current capability. The component utilizes an extremely thin, leadless 0503 package to optimize board space. Key electrical characteristics include a low forward voltage drop and high surge current handling. It operates within a temperature range of -55°C to +125°C and meets RoHS3 compliance standards.
Feature Summary
- Extremely thin and leadless package design for small surface mounting
- Low forward voltage drop for improved efficiency
- High surge current capability for robust protection
- Ultra-high-speed switching performance
Applications
- Low profile surface mounted rectification
- Overvoltage protection circuits
- Space-optimized PCB designs
Procurement Notes
Verify the specific suffix (e.g., -HF) against the manufacturer's official datasheet to confirm RoHS compliance and packaging details. Ensure the 0503 package dimensions match your PCB footprint requirements. Confirm the 100mA current rating is sufficient for your specific load conditions before finalizing procurement.
Selection Notes
Select this component when board space is limited due to its ultra-thin leadless form factor. It is suitable for applications requiring fast switching speeds and low forward voltage drops at moderate current levels. Ensure the operating environment stays within the specified -55°C to +125°C temperature range for reliable performance.
Part Context
This part belongs to Comchip Technology's Schottky Barrier Diode lineup, which emphasizes batch process design for excellent power dissipation and thermal resistance. The series is engineered for low-profile surface mount applications, offering better reverse leakage current characteristics compared to standard packages while maintaining high efficiency.
Replacement Considerations
Check for direct substitutes with identical 40V/100mA ratings and 0503 package dimensions. Verify that any replacement maintains the same low forward voltage and switching speed characteristics to ensure circuit compatibility without redesign.
