CDBF0530

Overview

The CDBF0530 is a Schottky barrier rectifier manufactured by Comchip Technology. It features a forward current of 500 mA and a reverse voltage rating of 30 V. The device utilizes a DFN surface-mount package, specifically the SOD-323F form factor (1005 metric). Key electrical characteristics include a low forward voltage drop and high efficiency, designed for small surface mounting applications.

Feature Summary

• Low forward voltage drop for improved efficiency
• Ultra-high-speed switching capability
• Low profile surface mount design

Applications

• Low voltage power supply rectification
• High frequency switching circuits
• Reverse polarity protection in portable devices

Procurement Notes

Verify the specific suffix (e.g., -HF) to confirm halogen-free compliance and RoHS status. Ensure the ordering code matches the required tape-and-reel or cut-tape packaging format. Cross-reference the datasheet revision date to confirm the latest thermal and electrical specifications before finalizing procurement.

Selection Notes

Select this component when a compact footprint is required alongside moderate current handling. The SOD-323F package offers space savings compared to standard axial leads. Verify that the 30 V reverse voltage rating exceeds the peak inverse voltage in the target circuit to ensure reliable operation under all conditions.

Part Context

This part belongs to Comchip's CDBF series of Schottky diodes. These components are engineered for general-purpose rectification where speed and low loss are prioritized. The series supports various voltage ratings and current capacities within a standardized surface-mount family.

Replacement Considerations

Check for direct equivalents with identical 500 mA current and 30 V voltage ratings. Ensure replacement parts maintain the same SOD-323F footprint and pinout configuration to avoid PCB redesign.
