1N3766R

Single Diodes Overview

The Microchip Technology 1N3766R is a silicon standard recovery rectifier diode housed in a DO-203AB (DO-5) stud-mount package. It features a maximum repetitive peak reverse voltage of 800 V and a continuous forward current rating of 35 A. The device exhibits a maximum non-repetitive surge forward current of 475 A on a half-sine wave. Electrical characteristics include a maximum DC blocking voltage of 800 V, a maximum RMS reverse voltage of 560 V, and a maximum forward voltage of 1.4 V at 110 A. The junction temperature range spans from -65 °C to 190 °C.

Single Diodes Feature Summary

• Standard polarity configuration with the stud serving as the cathode terminal
• Reverse polarity variant where the stud functions as the anode terminal
• High surge current capability for robust transient handling
• Glass passivated die construction for enhanced reliability

Single Diodes Applications

• General purpose rectification circuits
• Industrial power conversion systems
• High voltage DC power supplies

Single Diodes Procurement Notes

Verify the specific manufacturer source, as the 1N3766R designation is utilized by multiple vendors including Microchip, Vishay, and GeneSiC. Confirm that the reverse polarity suffix 'R' corresponds to the required anode-stud configuration for your mechanical design. Ensure compliance with RoHS or REACH requirements based on the specific supplier's production batch and environmental declarations.

Single Diodes Selection Notes

Select this component when a high-voltage standard recovery diode with a stud-mount interface is required. The 800 V rating distinguishes it from lower-voltage variants like the 1N3765R (50 V) and higher-voltage counterparts like the 1N3768R (1000 V). Consider the thermal management needs associated with the 190 °C maximum junction temperature and the 35 A continuous current capacity in your system design.

Single Diodes Part Context

This part belongs to the 1N3765 through 1N3768 series of silicon standard recovery diodes. The series covers reverse voltage ratings from 50 V to 1000 V while maintaining a consistent 35 A forward current rating. The 'R' suffix indicates a reverse polarity configuration, which is critical for applications requiring the stud to be connected to the positive rail rather than ground.

Single Diodes Replacement Considerations

The Vishay VS-1N3766R is a verified equivalent part number offering identical electrical specifications and package dimensions.
