ACDBA260-HF

Overview

The ACDBA260-HF is a surface-mount Schottky barrier rectifier manufactured by Comchip Technology. It features a single diode configuration housed in an SMA (DO-214AC) package. The device is rated for a maximum average forward rectified current of 2 Amperes and a repetitive peak reverse voltage of 60 Volts. Designed for low-loss high-frequency applications, it utilizes a metal-semiconductor junction to achieve a very low forward voltage drop and minimal reverse leakage current.

Feature Summary

• Schottky barrier construction ensures fast switching speeds and low power loss during operation.
• Low forward voltage drop minimizes heat generation and improves overall circuit efficiency.
• Encapsulated in a compact SMA (DO-214AC) surface-mount package for automated assembly.

Applications

• High-frequency DC-DC converter output rectification
• Free-wheeling diodes in inductive load circuits
• Polarity protection in power supply inputs

Procurement Notes

Verify the specific datasheet revision when sourcing to ensure compliance with RoHS directives and halogen-free status. Confirm that the ordering suffix matches the required packaging format, such as cut tape or reel, as these may vary by distributor. Cross-reference the manufacturer part number with official Comchip Technology documentation to validate authenticity and technical specifications before procurement.

Selection Notes

Select this component for circuits requiring efficient rectification at frequencies where standard PN junctions exhibit excessive reverse recovery losses. Ensure the operating ambient temperature remains within the specified range to maintain reliability. Verify that the peak inverse voltage rating exceeds the maximum transient voltages present in the application to prevent breakdown.

Part Context

This component belongs to the CDBA series of surface-mount Schottky rectifiers from Comchip Technology. It shares the SMA footprint with other variants in the family but is distinguished by its specific 60V voltage rating and 2A current capacity. This series is designed to replace larger through-hole rectifiers in space-constrained modern electronic designs.

Replacement Considerations

Compatible substitutes include the CDBA260-G and CDBA260-LR-HF from the same manufacturer. Other manufacturers offer equivalent SMA-packaged 2A 60V Schottky diodes, provided they meet the same electrical ratings and thermal characteristics.
