ACDBB540-HF

Single Diodes Overview

The ACDBB540-HF is a surface-mount Schottky barrier rectifier manufactured by Comchip Technology. It features a single diode configuration in a DO-214AA (SMB) package. Key electrical parameters include a repetitive reverse voltage of 40 V and an average forward current rating of 5 A. The device exhibits a maximum forward voltage drop of 0.55 V at the rated current and a peak forward surge current capability of 150 A. Reverse leakage current is specified at 0.5 mA, with an operating junction temperature range from -55°C to +125°C.

Single Diodes Feature Summary

• Utilizes majority carrier conduction for low forward voltage drop and high switching efficiency.
• Constructed with silicon technology for robust thermal performance and reliability.
• Designed for surface mount mounting on small PCB areas using standard leadless packages.

Single Diodes Applications

• High-frequency power supply rectification
• DC-DC converter output stages
• Free-wheeling diodes in inductive load circuits

Single Diodes Procurement Notes

Verify component authenticity through official manufacturer channels or authorized distributors. Confirm RoHS compliance status as it may be in transition. Ensure the specific suffix matches the required packaging format, such as cut tape or reel quantities, prior to ordering to align with assembly line requirements.

Single Diodes Selection Notes

Select this component when a 40 V blocking voltage and 5 A continuous current capacity are required in a compact SMB footprint. Consider the low forward voltage characteristic for improved efficiency in low-voltage DC systems. Verify that the thermal management design supports the specified junction temperature limits during operation.
