ACGRA4006-HF

Overview

The ACGRA4006-HF is a standard recovery rectifier diode manufactured by Comchip Technology. It features a maximum repetitive peak reverse voltage of 600 V and an average forward current rating of 1 A. The device utilizes a DO-214AC (SMA) surface-mount package. Key electrical characteristics include a maximum DC reverse current of 5 µA at rated voltage, a typical forward voltage of 1.1 V at 1 A, and a reverse recovery time of 2.5 µs. It operates within a junction temperature range of -55°C to +150°C and holds AEC-Q101 automotive qualification.

Feature Summary

• Automotive-grade reliability certified under the AEC-Q101 standard for robust performance in demanding environments.
• Glass-passivated construction provides enhanced protection against mechanical stress and chemical corrosion.
• Surface-mount design in a compact DO-214AC package facilitates automated pick-and-place assembly processes.

Applications

• General-purpose rectification in automotive electronic circuits
• DC-to-DC converter output stages
• Power supply freewheeling applications

Procurement Notes

Verify the specific suffix 'HF' confirms RoHS3 compliance during procurement. Confirm the package designation matches DO-214AC requirements for your PCB footprint. Ensure the AEC-Q101 qualification aligns with your system's automotive grade specifications. Cross-reference the manufacturer part number with distributor codes to prevent ordering errors.

Selection Notes

Select this component when a 600 V blocking capability is required for high-voltage DC circuits. The 1 A current rating suits moderate power applications where space constraints favor surface-mount technology. Consider the 2.5 µs reverse recovery time for general frequency operations rather than high-speed switching scenarios.

Part Context

This part belongs to the ACGRA series of glass-passivated silicon rectifiers from Comchip Technology. The series covers various voltage ratings from 50 V to 1000 V within the same SMA package family. The ACGRA4006-HF specifically addresses the 600 V segment, offering a standardized solution for automotive and industrial power management designs requiring reliable single-diode rectification.

Replacement Considerations

Direct substitutes include other 1 A, 600 V SMA rectifiers such as the MBR160 or equivalent parts from major manufacturers. Verify that replacement components meet the same AEC-Q101 automotive qualification if required by the application. Ensure thermal and mechanical specifications match the original DO-214AC form factor.
