1N3166R

Single Diodes Overview

The Microchip Technology 1N3166R is a silicon rectifier diode designed for high-current power applications. It features a single-phase, one-element configuration housed in a DO-205AB metal package with stud-mount installation. The device supports a repetitive peak reverse voltage of 300V and a continuous forward current of 240A. It exhibits a maximum non-repetitive peak forward surge current of 3000A and a maximum forward voltage drop of 0.95V.

Single Diodes Feature Summary

• High-capacity current handling capability suitable for demanding power conversion tasks
• Robust thermal management through direct stud-mount attachment to heatsinks
• Standard recovery characteristics optimized for general-purpose rectification

Single Diodes Applications

• Industrial power supply rectification
• Motor drive systems

Single Diodes Procurement Notes

Verify the specific manufacturer source, as the 1N3166 designation has been produced by multiple vendors including New Jersey Semiconductor. Confirm that the 'R' suffix denotes the correct tape-and-reel or tray packaging variant required for your assembly process. Ensure compliance with RoHS status requirements, as historical versions may not be compliant. Cross-reference the datasheet revision to confirm electrical parameters match your design specifications before finalizing procurement.

Single Diodes Selection Notes

Select this component when a standard recovery silicon diode with high current capacity is required. The stud-mount package necessitates compatible mechanical mounting hardware and thermal interface materials. Evaluate the thermal resistance from junction to case to ensure adequate heat dissipation under continuous load conditions. Consider the forward voltage drop impact on overall system efficiency compared to alternative technologies.

Single Diodes Part Context

This part belongs to the legacy 1N series rectifier lineup, originally defined by military standards and later adopted by commercial manufacturers. Microchip Technology acquired assets from Microsemi, which previously manufactured these devices. The 1N3166R represents a specific commercial variant within this family, maintaining compatibility with original form, fit, and function specifications established for high-power industrial applications.

Single Diodes Replacement Considerations

Direct replacements include the 1N3166 from other qualified manufacturers such as New Jersey Semiconductor, provided electrical ratings and package dimensions are identical. Verify pinout orientation and cathode marking consistency. Alternative high-current diodes must match the 240A continuous current rating and 300V reverse voltage specification.
