1N1346AR

Single Diodes Overview

The 1N1346AR is a general-purpose rectifying diode manufactured by Microchip Technology. It features a maximum repetitive peak reverse voltage of 400 V and an average forward rectified current rating of 16 A. The device utilizes a stud mount configuration within the DO-4 (DO-203AA) package. Key electrical characteristics include a maximum DC forward voltage of 1.3 V at rated current and a maximum non-repetitive surge current capability of 250 A. The component operates with a maximum junction temperature of 175 °C and exhibits a low leakage current of 10 µA.

Single Diodes Feature Summary

Single Diodes Procurement Notes

Verify the specific suffix 'AR' against the official Microchip datasheet to confirm exact manufacturing lot or environmental compliance details. Ensure the mounting surface preparation matches the stud interface requirements. Confirm that the procurement channel provides genuine components with traceable documentation, as this is a specialized industrial-grade semiconductor.

Single Diodes Selection Notes

Select this component when a high-current, high-voltage rectifier is required in a compact stud-mount form factor. The 16 A continuous rating and 400 V blocking voltage make it suitable for medium-power AC-to-DC conversion. Consider the thermal resistance of the DO-4 package and the necessity of a heatsink compatible with stud mounting for optimal performance under load.

Single Diodes Part Context

This part belongs to the standard rectifier diode family from Microchip Technology, historically derived from established industry standards. The 1N1346 series is designed for robust industrial applications requiring reliable unidirectional current flow. The 'AR' designation typically indicates specific packaging or testing variations within the broader 1N1346 product line.

Single Diodes Replacement Considerations

Direct substitutes must match the 400 V reverse voltage, 16 A forward current, and DO-4 stud mount package. Verify pinout compatibility and thermal characteristics before swapping.
