Overview
The ACDBMS140-HF is a Schottky barrier rectifier manufactured by Comchip Technology. It features a single-phase configuration with a maximum average forward rectified current of 1 A and a peak repetitive reverse voltage of 40 V. The device utilizes silicon epitaxial planar chip technology within an SOD-123 surface-mount package. Key electrical characteristics include a low forward voltage drop and high surge capability, designed for efficient power conversion in compact electronic applications.
Feature Summary
- Low forward voltage drop for enhanced efficiency
- High surge current capability for robust operation
- Ultra-high-speed switching performance
- Guarding against overvoltage conditions
Applications
- Automotive electronics systems
- DC-DC converter circuits
- Power supply input rectification
Procurement Notes
Verify the specific suffix and marking code on the component body to ensure it matches the ACDBMS140-HF designation exactly. Confirm RoHS compliance status through the manufacturer's latest documentation before integration. Check for any recent product change notices that may affect pinout or material composition.
Selection Notes
Select this component when a low-profile surface-mount Schottky rectifier is required for 40V applications. Ensure the design accommodates the thermal dissipation limits of the SOD-123 package. Compare forward voltage specifications against alternative packages if board space allows for larger footprints.
Part Context
This part belongs to Comchip Technology's automotive-grade Schottky diode lineup. It shares functional similarities with other series like CDBA and CDBH but is distinguished by its specific SOD-123 form factor and AEC-Q101 qualification where applicable. It serves as a compact solution for modern miniaturized power management designs.
Replacement Considerations
Cross-reference with ACDBQC140L-HF for similar voltage and current ratings in different packages. Verify compatibility with CDBHM140L-HF if MBS packaging is acceptable instead of SOD-123.
