AU1PK-M3/84A

Overview

The AU1PK-M3/84A is a silicon ultrafast rectifier manufactured by Vishay General Semiconductor. It features a single diode configuration housed in the DO-220AA (SMP) surface-mount package. The device is rated for a maximum repetitive peak reverse voltage of 800V and an average forward rectified current of 1A. Key electrical characteristics include a maximum non-repetitive peak surge current of 30A and a typical reverse recovery time of 35ns. The component operates within a junction temperature range of -55°C to +175°C.

Feature Summary

• Ultrafast recovery characteristics suitable for high-frequency switching applications
• Plastic material molded compound meets UL flammability classification 94V-0
• Low profile surface mount design optimized for automated assembly processes

Applications

• High frequency DC-DC converters
• Free wheeling rectification in power supplies
• Snubber circuits in switch mode power supplies

Procurement Notes

Verify the specific suffix /84A corresponds to the required tape and reel packaging format before ordering. Confirm that the 800V rating aligns with the circuit's peak inverse voltage requirements. Ensure the DO-220AA footprint matches the PCB layout constraints. Check for RoHS compliance status if environmental regulations apply to the final assembly.

Selection Notes

Select this component when high efficiency and fast switching speeds are critical for reducing switching losses. The 800V rating provides sufficient margin for mains-derived power supplies. Consider the thermal performance of the DO-220AA package for heat dissipation needs. Compare against standard recovery diodes if lower cost is prioritized over speed.

Part Context

This part belongs to Vishay's AU series of ultrafast rectifiers designed for general purpose high-speed switching. The M3 suffix indicates lead-free termination and halogen-free molding compound. The /84A designation typically specifies the specific reel quantity and packaging method used by distributors.
