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.
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.
Applications
- High-frequency power supply rectification
- DC-DC converter output stages
- Free-wheeling diodes in inductive load circuits
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.
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.
Part Context
This part belongs to the CDBB series of SMD Schottky Barrier Rectifiers produced by Comchip Technology. The series focuses on providing reliable rectification solutions for space-constrained electronic designs. It shares common family characteristics such as silicon construction and surface-mount compatibility with other variants in the product line.
Replacement Considerations
Cross-reference with ACDBB560-HF for similar Schottky rectifier applications if voltage ratings differ. Verify pinout compatibility and thermal dissipation capabilities before substituting with generic equivalents.
