1N6544

Overview

The Microchip Technology 1N6544 is a high-speed ultra-fast recovery rectifier diode designed for demanding power conversion applications. It features a 500V repetitive peak reverse voltage and a 3A average forward rectified current capability. The device utilizes an A-PKG axial leaded package, ensuring robust mechanical stability for through-hole mounting. Key electrical characteristics include a maximum non-repetitive surge current of 75A and a low forward voltage drop to minimize conduction losses. With a typical reverse recovery time of 35ns, it offers superior switching performance compared to standard recovery diodes, making it suitable for high-frequency inverter and freewheeling circuits.

Feature Summary

Ultra-fast recovery characteristic for reduced switching losses
High thermal stability with extended junction temperature range
Robust axial leaded construction for reliable mounting

Applications

High-frequency inverter circuits
Freewheeling diode applications
DC-DC converter output rectification

Procurement Notes

Verify the specific suffix (e.g., /TR) against the required packaging format, as bulk reels differ from cut tape. Confirm RoHS compliance status for the specific manufacturing lot if environmental regulations apply. Ensure the axial lead spacing matches the target PCB footprint design before finalizing procurement orders.

Selection Notes

Select this component when fast reverse recovery is critical to minimize electromagnetic interference and heat generation. Compare the 3A current rating against the circuit's peak load requirements. Consider the A-PKG package dimensions for board space constraints versus alternative surface-mount options if available.

Part Context

This part belongs to Microchip's discrete semiconductor portfolio, specifically within the rectifier category. It serves as a legacy or specialized solution for high-voltage, medium-current applications where ultra-fast recovery is mandatory. The product line supports various industrial and commercial power supply designs requiring reliable diode switching.

Replacement Considerations

Direct substitutes must match the 500V/3A rating and ultra-fast recovery profile. Verify pinout compatibility for axial leads. Check datasheets for equivalent parts from other manufacturers offering similar reverse recovery times and forward voltage characteristics.
