ACDBMT1150-HF

Overview

The ACDBMT1150-HF is a low-profile Schottky barrier rectifier from Comchip Technology, designed for high-efficiency power conversion. It features an average forward current of 1A and a maximum repetitive reverse voltage of 150V. The device utilizes a SOD-123H-2 package, which is significantly thinner than standard SOD-123 variants to optimize board space. Key electrical characteristics include a forward voltage drop of 0.92V at rated current and a surge current capability of 30A. It operates within a temperature range of -55°C to +150°C and holds AEC-Q101 automotive qualification.

Feature Summary

• Automotive-grade reliability certified under AEC-Q101 standards
• Low-profile package design reduces height by 40% compared to standard SOD-123
• Ultra-high-speed switching with low forward voltage drop for improved efficiency
• High surge current capability with excellent thermal resistance

Applications

• Automotive electronics systems requiring robust rectification
• DC-DC converters in compact power modules
• Reverse polarity protection circuits
• Free-wheeling diodes in inductive load applications

Procurement Notes

Verify the specific suffix and packaging configuration when ordering, as availability may vary between cut tape, MouseReel, or reel formats. Confirm that the component meets the required AEC-Q101 qualification if used in automotive designs. Ensure the SOD-123H-2 footprint matches the PCB layout, noting its reduced profile dimensions compared to traditional packages. Cross-reference datasheet parameters against system requirements for voltage and current ratings.

Selection Notes

Select this component for applications demanding small form factors and high thermal performance. The low-profile SOD-123H-2 package is ideal for space-constrained designs where standard SOD-123 devices do not fit. Its AEC-Q101 certification makes it suitable for automotive environments. Consider the 150V reverse voltage rating and 1A current capacity to ensure adequate headroom for the specific circuit application.

Part Context

This part belongs to Comchip's CDBMT series of low-profile Schottky barrier rectifiers. The series is engineered to provide better power dissipation and lower reverse leakage current than standard counterparts. The 'AC' prefix typically denotes automotive qualification, aligning with the AEC-Q101 standard. The series offers various voltage ratings while maintaining consistent physical dimensions for easy integration into modern electronic assemblies.

Replacement Considerations

Direct replacements must match the SOD-123H-2 package and AEC-Q101 qualification. Verify that substitute parts offer equal or higher reverse voltage (150V) and forward current (1A) ratings. Ensure the replacement maintains similar forward voltage and thermal characteristics to preserve circuit efficiency.
