CDBF0520L

Overview

The CDBF0520L is a Schottky barrier rectifier manufactured by Comchip Technology, designed for surface-mount applications. It features a maximum DC reverse voltage (Vr) of 20 V and an average forward current (Io) of 500 mA. The device utilizes a SOD-323F package, providing a compact form factor suitable for space-constrained designs. Key electrical characteristics include a low forward voltage drop and high switching efficiency, typical of silicon epitaxial planar chip technology with metal-silicon junctions.

Feature Summary

• Low forward voltage drop for high efficiency
• Ultra-high-speed switching capability
• Guardring structure for overvoltage protection

Applications

• Low voltage, high frequency inverters
• Free-wheeling diode circuits
• Polarity protection applications

Procurement Notes

Verify the specific suffix designation when ordering, as variants such as CDBF0520L-HF exist within the product line. Confirm package type accuracy, as some listings may reference different footprints like DO-214AA or SOD-323F. Ensure compliance with RoHS requirements if applicable to the project specifications. Cross-reference datasheets from authorized distributors to confirm current availability status.

Selection Notes

Select this component for circuits requiring fast recovery times and low conduction losses at moderate current levels. The 20 V rating suits low-voltage power supplies and battery-operated devices. Consider thermal management requirements based on the small surface-mount package size. Compare against higher current variants if load demands exceed 500 mA average forward current.

Part Context

This part belongs to Comchip Technology's Schottky Barrier Rectifier series, which offers various voltage and current ratings. The CDBF0520L specifically targets applications needing compact packaging with reliable switching performance. It complements other surface-mount diodes in the manufacturer's portfolio designed for modern electronics manufacturing processes.

Replacement Considerations

Check for direct substitutes with identical 20 V / 500 mA ratings and SOD-323F footprint. Verify pinout compatibility and forward voltage characteristics before substitution.
