Overview
The CDBB340LR-HF is a surface-mount Schottky barrier rectifier manufactured by Comchip Technology. It utilizes silicon construction and operates as a single-diode component within the DO-214AA (SMB) package. The device supports a maximum repetitive peak reverse voltage of 40V and an average forward current of 5A. Key electrical characteristics include a low maximum forward voltage of 0.55V at 5A, a non-repetitive peak forward surge current capability of 150A, and a maximum reverse leakage current of 1mA at rated voltage. It functions reliably across a junction temperature range from -55°C to +150°C.
Feature Summary
- Low forward voltage design for enhanced efficiency
- Majority carrier conduction for fast switching
- Halogen-free compliant construction
Applications
- High-frequency rectification in power supplies
- Reverse polarity protection circuits
- Clamping diodes in electronic systems
Procurement Notes
Verify the specific ordering suffix against official manufacturer documentation to confirm compliance status and packaging details. Ensure the selected variant matches the required RoHS and halogen-free specifications for your assembly process. Cross-reference the JEDEC code with your PCB footprint requirements before finalizing procurement.
Selection Notes
Select this component when a high-current Schottky rectifier in an SMB package is required. The 5A rating and low forward voltage make it suitable for applications prioritizing thermal management and conversion efficiency. Confirm that the 40V reverse voltage rating exceeds the circuit's peak inverse voltage under all operating conditions.
