ACURB206-HF

Overview

The ACURB206-HF is a general-purpose switching diode manufactured by Comchip Technology, designed for surface-mount applications. It features an SMB (DO-214AA) package and supports a maximum repetitive reverse voltage of 800 V with a forward current rating of 2 A. The device is qualified under the AEC-Q101 standard for automotive reliability. Key electrical parameters include a peak forward surge current of 50 A and a maximum operating junction temperature of +150 °C. It operates within a temperature range of -55 °C to +150 °C.

Feature Summary

• AEC-Q101 qualified for automotive electronic systems
• High-temperature operation capability up to 150 °C
• Surface-mount SMB package design

Applications

• Automotive electronics circuits
• General-purpose rectification
• Switching applications in high-voltage environments

Procurement Notes

Verify the specific datasheet version when sourcing, as manufacturing updates may occur. Confirm that the component meets the required AEC-Q101 qualification standards for your specific automotive application. Ensure compatibility with the SMB/DO-214AA footprint during PCB layout. Check for RoHS compliance status if environmental regulations apply to your region.

Selection Notes

Select this component when an 800 V reverse voltage rating is required for high-side or flyback applications. The 2 A average forward current makes it suitable for moderate power switching tasks. The AEC-Q101 qualification is essential for automotive OEM designs requiring robust reliability. Consider the SMB package size constraints against available board space.

Part Context

Comchip Technology specializes in discrete semiconductors, including Schottky diodes, bridge rectifiers, and TVS devices. The ACURB206-HF belongs to their general-purpose rectifier line, distinct from their ultra-fast recovery or low-loss Schottky series. This product utilizes standard silicon technology optimized for high-voltage blocking capabilities rather than ultra-low forward voltage drop.

Replacement Considerations

Direct substitutes must match the 800 V / 2 A specification and DO-214AA/SMB package. Verify pinout compatibility and thermal characteristics before substitution. Cross-reference with other manufacturers offering AEC-Q101 qualified general-purpose diodes in the same footprint.
