1N3176

Single Diodes Overview

The Microchip Technology 1N3176 is a silicon power rectifier diode designed for high-current applications. It features a maximum average forward rectified current of 240 A and a repetitive peak reverse voltage (VRRM) of 1400 V. The device supports a non-repetitive peak surge current of 3000 A. It operates within a junction temperature range of -65 °C to 200 °C. The component utilizes a DO-205AB (DO-9) metal package with stud mounting and a single anode connection.

Single Diodes Feature Summary

• High thermal stability enabling operation up to 200 °C junction temperature
• Robust surge current handling capability of 3000 A
• Stud mount construction for efficient heat dissipation

Single Diodes Applications

• Industrial power conversion systems
• High-voltage rectification circuits
• Power supply units requiring high current capacity

Single Diodes Procurement Notes

Verify the manufacturer designation, as historical data indicates production by Solid State Inc. prior to acquisition. Confirm the specific datasheet version matches the required electrical tolerances. Ensure the DO-9 metal package dimensions align with the intended heatsink interface. Check for RoHS compliance status if environmental regulations apply to the final assembly.

Single Diodes Selection Notes

Select this component when a single-phase silicon rectifier with 240 A continuous current rating is required. The 1400 V reverse voltage rating suits medium-to-high voltage AC-to-DC conversion. The stud mount configuration is necessary for applications demanding direct thermal coupling to a chassis or heatsink rather than PCB mounting.

Single Diodes Part Context

This part belongs to the standard silicon power rectifier family. It serves as a discrete semiconductor solution for replacing older legacy designs in industrial equipment. The DO-9 package is a traditional metal case style often found in heavy-duty power electronics infrastructure.

Single Diodes Replacement Considerations

Cross-reference with other 1N3176 variants from different manufacturers such as Microsemi or Littelfuse. Verify that substitute parts maintain the identical 240 A current rating and 1400 V blocking voltage. Ensure mechanical compatibility of the stud thread and terminal configuration.
