1N2785

Single Diodes Overview

The Microchip Technology 1N2785 is a standard recovery rectifier diode designed for high-power applications. It features a maximum DC reverse voltage (Vr) of 400 V and an average rectified forward current (Io) of 22 A. The device utilizes a DO-4 (DO-203AA) stud mount package, suitable for robust industrial environments. Key electrical characteristics include a forward voltage drop of 1.2 V at 30 A and a maximum reverse leakage current of 10 µA at 400 V. It operates within a junction temperature range of -65°C to +200°C and exhibits a standard recovery time exceeding 500 ns.

Single Diodes Feature Summary

• High thermal stability with a junction temperature rating up to 200°C
• Robust mechanical construction via stud mount installation in DO-4 package
• Standard recovery characteristics suitable for general-purpose power conversion

Single Diodes Applications

• Industrial power supply rectification
• Battery charging circuits
• DC power distribution systems

Single Diodes Procurement Notes

Verify the specific manufacturing date code and lot traceability upon receipt, as lead times may vary significantly due to the specialized nature of through-hole power components. Confirm that the DO-4 mounting hardware requirements align with your chassis design before finalizing orders. Ensure compliance with relevant environmental regulations such as REACH status if applicable to your region.

Single Diodes Selection Notes

Select this component when a high-current, medium-voltage rectifier with superior thermal endurance is required. The 22 A continuous current rating and 400 V blocking capability make it distinct from lower-power alternatives. Consider the physical size and mounting constraints of the DO-4 package compared to surface-mount options during the initial circuit layout phase.

Single Diodes Part Context

This part belongs to the legacy standard rectifier family produced by Microchip Technology. It serves as a direct replacement for older military-grade or industrial-standard diodes previously manufactured under similar JEDEC numbering conventions. The component represents a bridge between traditional discrete semiconductor technology and modern high-reliability power electronics requirements.

Single Diodes Replacement Considerations

Direct substitutes must match the 400 V Vr, 22 A Io, and DO-4 package dimensions. Verify that any alternative offers equal or better thermal resistance and reverse leakage specifications.
