ACDBQC0240LR-HF

Single Diodes Overview

The ACDBQC0240LR-HF is a Schottky barrier rectifier manufactured by Comchip Technology. It features a single diode configuration in an SOD-923F (0402) surface-mount package. Key electrical parameters include a maximum repetitive reverse voltage (VRRM) of 40 V and an average forward rectified current (IF) of 200 mA. The device exhibits a low forward voltage drop (VF) of 500 mV at IF and a maximum reverse leakage current (IR) of 40 uA. It supports a forward surge current (IFSM) of 9 A and operates within a junction temperature range of -55°C to +150°C.

Single Diodes Feature Summary

• Automotive-grade reliability compliant with AEC-Q101 standards
• Low forward voltage drop for improved efficiency
• Minimal reverse leakage current
• Compact SOD-923F footprint for space-constrained designs

Single Diodes Applications

• Automotive electronics systems
• High-frequency switching circuits
• DC-DC converter output rectification

Single Diodes Procurement Notes

Verify the specific suffix 'LR' against the manufacturer's official datasheet to confirm it denotes automotive qualification or specific tape-and-reel packaging variations. Ensure the component matches the required AEC-Q101 certification if used in automotive applications. Cross-reference the part number with authorized distributors to avoid counterfeit components, as minor suffix changes can indicate different binning or packaging formats.

Single Diodes Selection Notes

Select this component when a compact SOD-923F package is required for 40V Schottky rectification in automotive environments. It is suitable for applications demanding low forward voltage and high thermal stability up to 150°C. Compare against standard commercial grade parts if automotive qualification is not strictly necessary, noting that this part offers enhanced reliability for harsh operating conditions.

Single Diodes Part Context

This part belongs to Comchip Technology's ACDBQC series of automotive-grade Schottky diodes. The series is designed to meet the rigorous demands of automotive electronics, offering robust performance in small outline packages. The ACDBQC0240LR-HF specifically targets low-current, high-voltage rectification needs in modern vehicle electronic control units and power management modules.

Single Diodes Replacement Considerations

Check for direct substitutes such as the ACDBQC140L-HF from the same manufacturer, which shares similar automotive qualifications but differs in current rating (1A vs 200mA). Verify pinout compatibility and thermal characteristics before substituting with non-automotive grade equivalents.
