ACDBQC00340-HF

Overview

The ACDBQC00340-HF is a surface-mount Schottky barrier diode manufactured by Comchip Technology. It features a single diode configuration housed in an SOD-923F-2 package, also identified as 0402C. The device supports a maximum repetitive reverse voltage (Vrrm) of 40 V and an average forward current (If) of 30 mA. Key electrical characteristics include a maximum forward voltage (Vf) of 500 mV at the rated current, a peak forward surge current (Ifsm) of 9 A, and a maximum reverse leakage current (Ir) of 40 uA. It operates within a junction temperature range of -55°C to +150°C.

Procurement Notes

Verify the specific ordering suffix and marking code during procurement to ensure compliance with project requirements. Confirm that the component meets the necessary automotive qualification standards if used in safety-critical systems. Cross-reference datasheet revisions to ensure compatibility with existing design specifications before finalizing orders.

Selection Notes

Select this component when a compact, automotive-qualified Schottky diode is required for low-current applications. The SOD-923F package offers a small footprint compared to larger diodes. Ensure the circuit design accounts for the 40 V reverse voltage rating and 30 mA forward current limits to maintain reliable operation under all expected load conditions.

Part Context

This part belongs to Comchip Technology's ACDBQC series of automotive Schottky diodes. The series is designed to meet the rigorous demands of automotive electronics, providing robust performance in harsh environments. The ACDBQC00340-HF specifically targets applications needing high reliability in a minimal surface-mount form factor.

Replacement Considerations

Direct replacements must match the SOD-923F package, 40 V rating, and 30 mA current capacity. Verify that any substitute component also holds AEC-Q101 certification if automotive use is intended. Check forward voltage and leakage current specifications to ensure equivalent thermal and electrical performance.
