ACDBMT140-HF

Single Diodes Overview

The ACDBMT140-HF is a low-profile Schottky barrier rectifier manufactured by Comchip Technology. It features a single diode configuration with a maximum repetitive reverse voltage of 40 V and an average forward current rating of 1 A. The device utilizes silicon epitaxial planar chip technology with a metal-silicon junction, offering ultra-high-speed switching capabilities. Designed for surface mount applications in the SOD-123H-2 package, it provides excellent power dissipation and thermal resistance. The component meets automotive reliability standards through AEC-Q101 qualification.

Single Diodes Feature Summary

• Low profile package design that is thinner than standard SOD-123 variants
• AEC-Q101 qualified for automotive electronic applications
• Ultra-high-speed switching with low forward voltage drop
• High surge capability and guarding for overvoltage protection

Single Diodes Applications

• Automotive electronics systems requiring AEC-Q101 compliance
• DC-DC converter circuits
• Power supply freewheeling diodes
• Reverse polarity protection circuits

Single Diodes Procurement Notes

Verify the specific suffix 'HF' indicates lead-free composition compliant with environmental standards. Confirm the package designation matches SOD-123H-2 dimensions for PCB layout compatibility. Ensure the AEC-Q101 qualification status is required for the target application environment. Cross-reference the manufacturer part number to distinguish from non-automotive grade equivalents within the CDBMT series.

Single Diodes Selection Notes

Select this component when automotive reliability certification is mandatory for low-voltage rectification tasks. The low-profile form factor suits space-constrained designs compared to standard SOD-123 packages. Consider the 40 V reverse voltage rating against peak circuit voltages to ensure adequate margin. Evaluate the 1 A current capacity against continuous load requirements and thermal management constraints.

Single Diodes Part Context

This part belongs to the ACDBMT series, which represents the automotive-grade extension of Comchip's CDBMT low-profile Schottky rectifiers. While the standard CDBMT series focuses on general industrial efficiency, the ACDBMT variant specifically incorporates AEC-Q101 qualification processes. It shares the physical footprint advantages but adheres to stricter automotive quality control protocols.

Single Diodes Replacement Considerations

Direct substitutes include other AEC-Q101 qualified Schottky diodes in the SOD-123H-2 package with 40 V and 1 A ratings. Verify pinout compatibility and forward voltage characteristics before substitution. Non-qualified equivalents like the standard CDBMT140-HF may fit physically but lack automotive certification.
