Overview
The AES2JF-HF is an automotive-grade Schottky barrier rectifier manufactured by Comchip Technology. It features a single diode configuration in an SMAF-2 surface-mount package. Key electrical specifications include a maximum repetitive peak reverse voltage (VRRM) of 600 V and an average forward rectified current (IF) of 2 A. The device exhibits a maximum forward voltage drop (VF) of 1.15 V at rated current and a low reverse leakage current (IR) of 5 µA. It supports a maximum surge forward current (IFSM) of 50 A and operates within a junction temperature range of -55 °C to +150 °C. The component holds AEC-Q101 qualification for automotive reliability.
Feature Summary
- Automotive-grade reliability certified under AEC-Q101 standards
- Low forward voltage drop for improved power efficiency
- Fast switching characteristics with minimal reverse recovery charge
- High thermal stability suitable for demanding environments
Applications
- Automotive DC-DC converters
- Power supply output rectification
- Freewheeling diodes in motor control circuits
- Reverse polarity protection in vehicle electronics
Procurement Notes
Verify the specific datasheet revision and AEC-Q101 certification status directly with Comchip Technology or authorized distributors before integration. Confirm that the SMAF-2 footprint matches your PCB design guidelines. Ensure that thermal management strategies account for the specified maximum junction temperature limits during operation.
Selection Notes
Select this component when a 600 V blocking capability is required in a compact SMAF-2 package. It is suitable for applications needing 2 A continuous current with high efficiency. Consider the 1.15 V forward voltage drop impact on system losses. Verify compatibility with automated assembly processes due to the surface-mount form factor.
Part Context
This part belongs to Comchip Technology's AES series of automotive Schottky diodes. The series is designed to meet stringent automotive quality requirements. The SMAF-2 package offers a small footprint compared to traditional DO-214AC (SMA) packages, allowing for denser circuit board layouts in space-constrained automotive modules.
Replacement Considerations
Check for direct pin-compatible alternatives from other manufacturers that meet AEC-Q101 standards. Ensure substitute parts match the 600 V VRRM, 2 A IF, and SMAF-2 package dimensions. Verify equivalent VF and IR specifications to maintain system performance.
