ACDBA1100LR-HF

Overview

The ACDBA1100LR-HF is a Schottky Barrier Rectifier manufactured by Comchip Technology. It features a 100V repetitive peak reverse voltage and a 1A average forward rectified current. The device utilizes the DO-214AC (SMA) surface-mount package with two pins. It is designed for low power loss, high efficiency, and ultra-high-speed switching applications.

Feature Summary

• Low forward voltage drop for high efficiency
• Ultra-fast switching capability
• Guardring structure for overvoltage protection

Applications

• Automotive electronics systems
• DC-DC converters
• Power supply units

Procurement Notes

Verify the specific suffix 'LR' indicates AEC-Q101 automotive qualification status against official manufacturer documentation. Confirm RoHS compliance and halogen-free status as stated in product descriptions. Ensure ordering details match the exact part number to avoid functional discrepancies.

Selection Notes

Select this component for circuits requiring 100V reverse blocking and 1A continuous current handling. The SMA package suits space-constrained designs. Verify thermal management requirements for the operating temperature range specified in the datasheet.

Part Context

This diode belongs to Comchip's SMD Schottky Barrier Rectifier series. These devices are silicon epitaxial planar chips with metal-silicon junctions. The series emphasizes low profile and optimized board space utilization for modern surface-mount assembly processes.

Replacement Considerations

Check for direct substitutes within the same voltage and current ratings. Verify pinout compatibility and package dimensions before substitution.
