ACDBA240-HF

Overview

The ACDBA240-HF is a Schottky barrier rectifier manufactured by Comchip Technology, designed for surface-mount applications in the DO-214AC (SMA) package. It features a maximum repetitive peak reverse voltage of 40 V and an average forward rectified current of 2 A. The device utilizes silicon technology with a low forward voltage characteristic to minimize conduction losses. It is qualified under the AEC-Q101 standard for automotive reliability. Key electrical parameters include a maximum DC reverse voltage of 40 V, a peak pulse forward current rating, and a specified leakage current of 500 µA at 40 V. The component operates within a temperature range suitable for demanding environments.

Feature Summary

• Automotive-grade qualification compliant with AEC-Q101 standards
• Low forward voltage drop for improved power efficiency
• Majority carrier conduction ensuring fast switching performance
• Glass passivated junction for enhanced environmental stability

Applications

• Automotive electronics systems requiring robust rectification

Procurement Notes

Verify the specific ordering suffix and packaging configuration against the manufacturer's latest documentation before procurement. Confirm that the AEC-Q101 qualification status aligns with your system's automotive reliability requirements. Ensure the DO-214AC footprint matches your PCB design guidelines. Cross-reference the datasheet revision date to guarantee parameter accuracy during the sourcing phase.

Selection Notes

Select this component when a high-current Schottky rectifier is required for automotive or industrial applications. The 2 A current rating supports moderate power levels while the 40 V breakdown voltage suits low-voltage DC systems. Consider the SMA package size for space-constrained designs. Evaluate the thermal dissipation capabilities relative to the expected ambient operating conditions and circuit load profiles.

Part Context

This part belongs to Comchip Technology's line of surface-mount Schottky diodes. The series is engineered to replace through-hole equivalents in modern automated assembly processes. The DO-214AC form factor provides a compact solution compared to larger axial packages. The product family emphasizes reliability and consistent electrical performance across varying temperature ranges.

Replacement Considerations

Check for direct pin-compatible alternatives from other manufacturers offering identical DO-214AC footprints. Verify that substitute parts meet the same 2 A current and 40 V voltage ratings. Ensure any replacement also holds relevant automotive certifications if used in regulated sectors.
