Overview
The CDBB1100LR-HF is a Schottky barrier rectifier manufactured by Comchip Technology, designed for surface mount applications. It features a single diode configuration within a DO-214AA (SMB) package. The device supports a maximum repetitive reverse voltage of 100 V and an average forward current of 1 A. Key electrical parameters include a forward voltage of 0.85 V at rated current and a reverse leakage current of 0.5 mA. It withstands a forward surge current of 30 A and operates reliably across a temperature range from -55°C to +150°C.
Feature Summary
- Low forward voltage drop for enhanced efficiency
- Ultra-low reverse leakage current
- High surge current capability
- Guarding against overvoltage conditions
Applications
- DC-DC converters
- Power supply circuits
- Free-wheeling diodes in inductive loads
- Overvoltage protection stages
Procurement Notes
Verify the specific suffix 'LR' corresponds to halogen-free or lead-free compliance requirements as defined by Comchip Technology documentation. Confirm that the DO-214AA footprint matches the target PCB design. Ensure the operating environment remains within the specified -55°C to +150°C thermal limits to maintain reliability.
Selection Notes
Select this component when low forward voltage and minimal reverse leakage are critical for system efficiency. The SMB package offers a balance between current handling and board space constraints compared to smaller SOD packages. Verify that the 100 V rating provides sufficient headroom for the specific circuit's peak inverse voltage scenarios.
Part Context
This part belongs to Comchip's Low VF Low IR SMD Schottky Barrier Rectifiers series. It shares functional similarities with other models in the CDBB family, such as the CDBB1150LR-HF, which offers higher voltage ratings. The series emphasizes improved thermal resistance and reduced power loss compared to standard Schottky diodes.
Replacement Considerations
Direct substitutes within the same series include CDBB1150LR-HF for higher voltage tolerance. Cross-family replacements like CDBA560-HF may require verification of package compatibility and current ratings.
