1N3170R

Single Diodes Overview

The 1N3170R is a silicon power rectifier manufactured by Microchip Technology, housed in the DO-205AB (DO-9) stud-mount package. It features a maximum repetitive reverse voltage of 600V and an average forward current rating of 300A. The device supports a non-repetitive peak forward surge current of 6250A and operates within a junction temperature range of -65°C to 200°C. Classified as a standard rectifier with a reverse recovery time exceeding 500ns, it utilizes a single-element configuration for high-efficiency power conversion applications.

Single Diodes Feature Summary

• High current handling capability suitable for heavy-duty power systems
• Robust thermal performance with extended operating temperature range up to 200°C
• Stud-mount construction for efficient heat dissipation and mechanical stability

Single Diodes Applications

• Industrial power supply units
• Motor drive rectification circuits
• Welding equipment power stages

Single Diodes Procurement Notes

Verify manufacturer origin carefully, as sources list both Microchip Technology and Microsemi. Confirm the specific datasheet version matches your design requirements regarding thermal resistance and mounting torque specifications. Ensure the component meets necessary environmental compliance standards for your target market before finalizing procurement orders.

Single Diodes Selection Notes

Select this component when high average current capacity and ruggedness are required over fast switching speeds. The standard rectifier characteristics make it ideal for low-frequency AC-to-DC conversion where reverse recovery speed is not critical. Evaluate thermal management solutions to maintain junction temperatures within the specified 200°C limit during continuous operation.

Single Diodes Part Context

This part belongs to the family of silicon power rectifiers designed for industrial-grade reliability. Originally associated with Microsemi Corporation, production has transitioned under Microchip Technology following corporate acquisitions. The DO-205AB package remains a standard form factor for high-power diodes requiring direct heatsink mounting.

Single Diodes Replacement Considerations

AW0785 from Aftermarket IR Industrial Controls is documented as a replacement for the 1N3170R. Verify electrical parameters and pinout compatibility before substitution.
