ACGRA4005-HF

Overview

The ACGRA4005-HF is a surface-mount standard recovery rectifier manufactured by Comchip Technology. It features a DO-214AC (SMA) package and supports an average forward current of 1A with a maximum repetitive peak reverse voltage of 500V. The device exhibits a maximum instantaneous forward voltage of 1.1V at 1A and a low DC reverse current of 5µA at rated blocking voltage. It is qualified to AEC-Q101 standards for automotive applications and operates within a junction temperature range of -55°C to +150°C.

Feature Summary

• Automotive-grade reliability certified under AEC-Q101 standards
• Glass-passivated silicon junction ensures stable performance
• DO-214AC molded plastic case with UL flammability classification 94V-0
• Built-in strain relief for enhanced mechanical durability

Applications

• General-purpose rectification in automotive electronic circuits
• DC-to-DC converter output stages
• Power supply freewheeling diodes
• Reverse polarity protection in vehicle systems

Procurement Notes

Verify the specific suffix 'HF' confirms RoHS compliance and halogen-free status as per manufacturer specifications. Confirm the DO-214AC package variant matches design footprint requirements. Ensure AEC-Q101 qualification is required for the target application environment. Cross-reference datasheet revisions to confirm electrical characteristics remain consistent with current production batches.

Selection Notes

Select this component when automotive reliability and surface-mount efficiency are prioritized over through-hole alternatives. The 500V rating provides sufficient margin for standard 12V or 24V automotive systems. Consider the SMA package dimensions for PCB space constraints. Evaluate thermal management needs based on the 1A continuous current capability and operating temperature limits.

Part Context

This part belongs to the ACGRA series of glass-passivated general-purpose rectifiers from Comchip Technology. The series offers various voltage ratings from 50V to 1000V in the same DO-214AC package, allowing for design flexibility. The 'HF' designation indicates environmental compliance, while the 'A' prefix often denotes automotive qualification in this product line.

Replacement Considerations

Direct substitutes include other AEC-Q101 qualified SMA rectifiers with 1A current and 500V reverse voltage ratings. Verify pinout compatibility and forward voltage characteristics before substitution. Generic replacements may lack the specific automotive certification required for safety-critical systems.
