Overview
The ACDBMS240-HF is an automotive-grade Schottky barrier rectifier manufactured by Comchip Technology. It features a 40V repetitive reverse voltage rating and a 2A average forward current capability. The device utilizes a low-profile SOD-123F surface-mount package, designed for high efficiency and low power loss. It operates within a junction temperature range of -55°C to +150°C and holds AEC-Q101 qualification for automotive reliability.
Feature Summary
- AEC-Q101 qualified for automotive applications
- Low profile SOD-123F package design
- High surge current capability
- Ultra-fast switching characteristics
Applications
- Automotive electronics protection
- DC-DC converter output rectification
- Free-wheeling diode in inductive load circuits
- Power supply input protection
Procurement Notes
Verify the specific datasheet revision and AEC-Q101 certification status directly with Comchip Technology or authorized distributors before integration. Confirm that the SOD-123F footprint matches the target PCB layout requirements. Ensure thermal management strategies account for the specified operating temperature range during final system validation.
Selection Notes
Select this component when automotive reliability standards are mandatory and space constraints require a low-profile surface-mount solution. The 40V rating suits low-voltage DC systems, while the 2A current capacity supports moderate power loads. Compare thermal resistance values against similar packages if heat dissipation is a critical design constraint.
Part Context
This part belongs to Comchip's ACDBMS series of automotive Schottky diodes. The series emphasizes robustness in harsh environments through AEC-Q101 compliance. The SOD-123F form factor offers a compact alternative to standard packages, facilitating denser circuit board layouts in modern automotive and industrial electronic assemblies.
Replacement Considerations
Check for direct cross-references from manufacturers like Vishay or Diodes Inc. offering identical 40V/2A SOD-123F specifications. Verify pinout compatibility and thermal performance metrics before substitution to ensure no redesign is required.
