1N1190AR

Single Diodes Overview

The GeneSiC Semiconductor 1N1190AR 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 a continuous forward current rating of 40 A. The device exhibits a maximum forward voltage of 1.1 V at 40 A and supports a surge non-repetitive forward current of 800 A for half-sine wave pulses. Operating junction temperatures range from -55 °C to 150 °C, with a thermal resistance of 1.25 °C/W.

Single Diodes Feature Summary

• High surge capability for handling transient current loads
• Reverse polarity configuration where the stud terminal functions as the anode
• Not sensitive to electrostatic discharge

Single Diodes Applications

• General purpose rectification in power supplies
• Industrial motor drive circuits
• Battery charging systems

Single Diodes Procurement Notes

Verify that the specific part number includes the 'R' suffix to confirm the reverse polarity configuration, as the standard variant utilizes a cathode stud. Confirm the manufacturer designation matches GeneSiC Semiconductor specifications. Ensure the package type aligns with the required DO-5 mounting hardware and torque specifications for reliable thermal management.

Single Diodes Selection Notes

Select this component when a 600 V blocking voltage and 40 A continuous current are required in a stud-mount form factor. The reverse polarity design is suitable for applications requiring the chassis or heatsink to be connected to the anode. Evaluate the thermal resistance against the available cooling solution to ensure the junction temperature remains within the specified operating range under load.

Single Diodes Part Context

This device belongs to the 1N1183A through 1N1190AR series of silicon standard recovery diodes. These components share identical electrical characteristics regarding current ratings and thermal properties, differing primarily in their voltage ratings. The series provides standardized solutions for high-power rectification tasks requiring robust mechanical mounting via threaded studs.

Single Diodes Replacement Considerations

Direct substitutes include other manufacturers' equivalents meeting the 1N1190 specification with identical 600 V, 40 A ratings and DO-5 packaging. Verify pinout compatibility, specifically the anode-stud configuration, before substitution.
