1N2789

Single Diodes Overview

The Microchip Technology 1N2789 is a silicon power rectifier diode designed for general-purpose applications. It features a standard recovery time exceeding 500ns, classifying it as a slow recovery device suitable for low-frequency switching. The component is housed in a DO-5 axial leaded package, providing robust mechanical stability for through-hole mounting. It supports a maximum repetitive peak reverse voltage of 400V and handles a continuous forward current of 70A. This configuration ensures reliable operation in high-power rectification circuits where thermal management and voltage withstand are critical.

Single Diodes Feature Summary

• High current handling capability for power supply applications
• Standard recovery characteristics for non-switching or low-frequency use
• Axial leaded construction for secure PCB integration

Single Diodes Applications

• Industrial power supplies
• Battery charging systems
• General-purpose rectification in AC-to-DC conversion

Single Diodes Procurement Notes

Verify the manufacturer source carefully, as multiple vendors including Microsemi and Microchip may list this part number. Confirm the specific package style matches your board design requirements. Ensure the datasheet specifies the exact electrical ratings for the batch being procured to avoid compatibility issues with existing circuit designs.

Single Diodes Selection Notes

Select this component when high current capacity is required alongside moderate reverse voltage blocking. The standard recovery time makes it unsuitable for high-frequency switching applications; consider fast recovery alternatives if switching speeds exceed typical line frequencies. Evaluate thermal dissipation needs based on the 70A rating and ambient operating conditions.

Single Diodes Part Context

This diode belongs to the family of silicon power rectifiers manufactured by Microchip Technology and its predecessor entities like Microsemi. These components are standardized under the 1N series numbering system, indicating compliance with established semiconductor industry specifications for discrete power devices used in heavy-duty electronic equipment.

Single Diodes Replacement Considerations

Direct substitutes include other 1N-series diodes with identical or higher voltage and current ratings. Verify pinout compatibility for DO-5 packages. Cross-reference with Microsemi datasheets for equivalent part numbers that maintain the same electrical performance profile.
