ACDBN1100-HF

Overview

The ACDBN1100-HF is a silicon Schottky barrier rectifier manufactured by Comchip Technology, designed for surface-mount applications. It features a single diode configuration housed in a 1206 (3216 metric) package. The device supports an average forward current of 1 A and a repetitive reverse voltage of 100 V. Key electrical parameters include a maximum forward voltage of 760 mV at rated current, a peak forward surge current capability of 20 A, and a reverse leakage current of 200 uA. It is qualified to the AEC-Q101 standard for automotive reliability.

Feature Summary

• Automotive-grade qualification compliant with AEC-Q101 standards
• Low profile surface-mount construction in a 1206 package
• Silicon epitaxial planar chip technology for robust performance

Applications

• Automotive electronics systems requiring AEC-Q101 compliance
• General-purpose rectification in surface-mount circuits
• Overvoltage protection applications

Procurement Notes

Verify component status prior to design finalization as the ACDBN1100-HF is listed as obsolete or discontinued by the manufacturer. Confirm availability through authorized distributors or secondary market sources if procurement is required. Ensure that any substitute components maintain equivalent AEC-Q101 automotive qualification and package dimensions to preserve board compatibility and system reliability standards.

Selection Notes

Select this component when automotive reliability certification is mandatory for low-voltage rectification tasks. The 1206 package offers a balance between current handling capacity and board space efficiency. Engineers should consider the specific forward voltage drop characteristics for thermal management calculations. Verify that the 100 V reverse voltage rating exceeds the maximum circuit operating voltage with adequate safety margin.

Part Context

This part belongs to Comchip Technology's portfolio of Schottky diodes and rectifiers. The ACDBN series specifically targets automotive and industrial sectors where standardized surface-mount footprints are preferred. It complements other variants in the lineup that offer different voltage ratings or current capacities while maintaining consistent packaging and automotive qualification standards.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Designers must identify alternative components that match the 1206 footprint, 1 A/100 V specifications, and AEC-Q101 qualification independently.
