Overview
The ACURN105-HF is a surface-mount ultra-fast recovery rectifier manufactured by Comchip Technology. It features a maximum average forward rectified current of 1.0 A and a repetitive peak reverse voltage of 1000 V. The device is designed for high-speed switching applications and meets AEC-Q101 automotive qualification standards. It utilizes a compact SOD-123 package, offering low profile and leadless construction suitable for automated surface-mount assembly processes.
Feature Summary
- Ultra-fast recovery characteristics optimized for high-frequency switching operations
- Automotive-grade reliability compliant with AEC-Q101 qualification standards
- Leadless surface-mount construction facilitating high-speed automated placement
Applications
- Automotive power supply circuits requiring high-voltage isolation
- High-frequency DC-DC converter output rectification
- Free-wheeling diode applications in motor control systems
Procurement Notes
Verify the specific datasheet revision to confirm package dimensions and thermal characteristics. Ensure the ordering suffix matches the required tape-and-reel quantity if applicable. Cross-reference the AEC-Q101 certification status with the manufacturer's official documentation to validate automotive suitability for your specific design requirements.
Selection Notes
Select this component when designing circuits that require 1000 V reverse blocking capability with 1 A continuous current handling. The ultra-fast recovery time makes it suitable for high-frequency topologies where standard rectifiers would exhibit excessive reverse recovery losses. Consider the SOD-123 footprint constraints during PCB layout planning.
Part Context
This part belongs to Comchip’s ACURN series of automotive ultra-fast recovery rectifiers. The series provides solutions for high-efficiency power conversion in demanding environments. The ACURN105-HF specifically addresses the need for high-voltage, high-speed switching in compact surface-mount packages, supporting modern miniaturization trends in electronic design.
Replacement Considerations
Check for direct substitutes within the same voltage and current ratings from other manufacturers. Verify pinout compatibility and thermal performance metrics before substitution. Ensure any alternative component also meets AEC-Q101 requirements if automotive application is mandatory.
