1N3289R

Single Diodes Overview

The Microchip Technology 1N3289R is a high-current silicon rectifier diode designed for stud mount applications. It features a maximum repetitive peak reverse voltage of 200 V and a maximum average on-state current of 100 A. The device utilizes the DO-205AA (DO-8) package with a cathode-to-stud configuration. Key electrical parameters include a forward voltage of 1.2 V at 200 A and a maximum junction temperature range of -65°C to +200°C.

Single Diodes Feature Summary

• High current handling capability with 100 A average rectified current rating
• Robust thermal performance supporting junction temperatures up to 200°C
• Stud mount construction for efficient heat dissipation in power electronics

Single Diodes Applications

• Industrial power conversion systems
• High current DC power supplies
• Welding equipment rectification circuits

Single Diodes Procurement Notes

Verify the specific suffix 'R' indicates the cathode-to-stud configuration as documented in official datasheets. Confirm RoHS compliance status, as standard versions may not meet all environmental directives. Ensure mounting hardware compatibility with the DO-205AA flange dimensions before procurement.

Single Diodes Selection Notes

Select this component when a 200 V reverse voltage rating and 100 A continuous current are required. The stud mount design necessitates appropriate thermal interface materials and torque specifications. Compare against the non-suffixed 1N3289 if anode-to-stud orientation is acceptable for the circuit layout.

Single Diodes Part Context

This part belongs to the 1N3288 through 1N3297 series of high current rectifiers from Microchip Technology. The series offers various voltage ratings from 100 V to 1400 V while maintaining a consistent 100 A current capacity and DO-8 package form factor for interchangeability in high-power designs.

Single Diodes Replacement Considerations

Direct substitutes within the same family include 1N3288R (100 V) or 1N3290R (300 V), provided voltage ratings align with system requirements. Verify that the replacement maintains the cathode-to-stud polarity and identical thermal resistance characteristics.
