1N3289AR

Single Diodes Overview

The Microchip Technology 1N3289AR is a standard recovery rectifier diode designed for high-current applications. It features a maximum DC reverse voltage of 200 V and an average forward rectified current rating of 150 A. The device utilizes a DO-205AA (DO-8) stud mount package, suitable for robust industrial environments. It operates within a junction temperature range of -65°C to +200°C. Key electrical characteristics include a maximum forward voltage of 1.1 V at 200 A and a reverse leakage current of 200 µA at 200 V.

Single Diodes Feature Summary

• High thermal stability with a maximum junction temperature of 200°C
• Robust mechanical construction via stud mount packaging
• Standard recovery speed characteristics for general-purpose rectification

Single Diodes Applications

• Industrial power supply rectification
• Welding equipment power stages
• Heavy-duty motor drive inverters

Single Diodes Procurement Notes

Verify the specific suffix 'AR' against official Microchip documentation to confirm if it denotes a specific tape-and-reel variant or packaging distinction compared to the base '1N3289A'. Ensure compliance requirements are met as the component may not be RoHS compliant. Confirm lead times directly with authorized distributors due to potential manufacturing changes.

Single Diodes Selection Notes

Select this component when high current handling up to 150 A is required in a compact stud-mount form factor. The 200 V reverse voltage rating suits medium-voltage AC-to-DC conversion tasks. Consider the 200°C operating limit for high-temperature environments where standard silicon limits would fail. Ensure adequate heatsinking is provided for the stud mount interface.

Single Diodes Part Context

This part belongs to the 1N3289 series of high-power rectifiers manufactured by Microchip Technology. These devices are engineered for durability in demanding power electronics applications. The series offers a balance of high current capacity and voltage blocking capability in a standardized DO-205AA outline.

Single Diodes Replacement Considerations

Cross-reference with other 150 A, 200 V stud-mount rectifiers from manufacturers like Vishay or Littelfuse. Verify that replacement parts match the exact pinout, mounting hole dimensions, and thermal resistance specifications of the DO-205AA package.
