1N1190

Single Diodes Overview

The GeneSiC Semiconductor 1N1190 is a silicon standard recovery rectifier diode housed in a DO-5 (DO-203AB) stud-mount package. It features a maximum repetitive peak reverse voltage of 600 V and supports a continuous forward current of 35 A. The device exhibits a maximum surge non-repetitive forward current of 595 A under half-sine wave conditions. Electrical characteristics include a maximum DC blocking voltage of 420 V, a thermal resistance from junction to case of 0.25 °C/W, and a maximum forward voltage of 1.2 V at 35 A. Operating temperature ranges from -55°C to 150°C.

Single Diodes Feature Summary

• High surge capability for robust transient handling
• Stud base configuration for efficient thermal management
• Standard polarity with cathode stud or reverse polarity variant

Single Diodes Applications

• Industrial power supply rectification
• Motor drive circuits
• General purpose high-current rectification

Single Diodes Procurement Notes

Verify the specific suffix designation to confirm terminal polarity orientation, as the 'R' variant indicates reversed leads where the stud functions as the anode rather than the cathode. Confirm compliance with applicable military or industrial standards if required for the target application environment. Ensure mounting hardware matches the specified thread size for secure installation.

Single Diodes Selection Notes

Select this component for applications requiring high current capacity and reliable performance in demanding thermal environments. The low thermal resistance facilitates effective heat dissipation when mounted to appropriate heatsinks. Consider the 600 V rating for medium-voltage AC-to-DC conversion tasks where standard recovery characteristics are sufficient.

Single Diodes Part Context

This component belongs to the 1N1188 through 1N1190R series of silicon standard recovery diodes. The series offers varying reverse voltage ratings while maintaining consistent current handling capabilities. These devices are designed for general-purpose rectification in industrial and commercial power electronics systems.

Single Diodes Replacement Considerations

Compatible substitutes within the same series include the 1N1188 and 1N1189 models, which share identical package dimensions and current ratings but offer lower reverse voltage specifications.
