Overview
The CDBF43-HF is a single silicon Schottky barrier rectifier manufactured by Comchip Technology. It features a maximum repetitive peak reverse voltage of 30V and an average forward current rating of 200mA. The device utilizes a surface-mount SOD-323F (1005 metric) package, measuring approximately 1.6mm x 0.8mm x 0.7mm. Key electrical characteristics include a low forward voltage drop of 750mV at 100mA and a maximum reverse leakage current of 50µA at rated voltage. It supports a forward surge current of 3A and operates within a junction temperature range of -55°C to +150°C.
Feature Summary
- Schottky barrier construction for high switching efficiency
- Low forward voltage drop reduces power loss
- Lead-free finish with halogen-free compliance
- Automotive-grade reliability qualification
Applications
- Automotive electronics modules
- DC-DC converter output rectification
- Power supply freewheeling diodes
- Reverse polarity protection circuits
Procurement Notes
Verify the specific suffix against official Comchip Technology documentation to confirm exact electrical tolerances and packaging configurations. Ensure the component meets RoHS and halogen-free requirements for your assembly process. Cross-reference the datasheet revision date to validate parameter accuracy before finalizing procurement specifications.
Selection Notes
Select this component for applications requiring low-voltage rectification with minimal forward voltage drop. The SOD-323F package is suitable for space-constrained PCB layouts. Verify that the 30V reverse voltage rating exceeds the maximum circuit operating voltage with adequate margin. Consider the 200mA current limit when designing thermal management strategies.
Part Context
This part belongs to Comchip Technology's line of surface-mount Schottky diodes designed for general-purpose rectification. The product family emphasizes automotive reliability and compact form factors. The CDBF43-HF variant specifically targets low-current, low-voltage applications where efficiency and size are critical design constraints.
Replacement Considerations
Consult official manufacturer substitution guides for verified equivalents. Generic replacements must match the 30V reverse voltage, 200mA current rating, and SOD-323F package dimensions. Verify pinout compatibility and thermal performance characteristics before implementation.
