1N1184A

Single Diodes Overview

The GeneSiC Semiconductor 1N1184A is a silicon standard recovery rectifier diode housed in a DO-5 (DO-203AB) stud-mount package. It features a repetitive peak reverse voltage of 100 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 a thermal resistance from junction to case of 1.25 °C/W. Operating temperatures range from -55 °C to 150 °C, with a surge non-repetitive forward current capability of 800 A.

Single Diodes Feature Summary

• High surge current capability for robust transient handling
• Stud base configuration with standard polarity where the stud serves as the cathode
• Not sensitive to electrostatic discharge

Single Diodes Applications

• General purpose rectification
• Power supply circuits requiring high surge tolerance
• Industrial equipment power stages

Single Diodes Procurement Notes

Verify the specific part marking against the datasheet terminal configuration diagram to confirm polarity orientation. Ensure the mounting surface temperature does not exceed the specified limits during operation. Confirm that the stud thread specifications match the application hardware requirements before integration.

Single Diodes Selection Notes

Select this component when a 100 V blocking voltage and 40 A continuous current are required in a stud-mount form factor. Consider the 1.25 °C/W thermal resistance for heatsink design calculations. Evaluate the 800 A surge rating against potential inrush currents in the target circuit to ensure adequate safety margins.

Single Diodes Part Context

This device belongs to the 1N1183A through 1N1190AR series of silicon standard recovery diodes manufactured by GeneSiC Semiconductor. All members of this family share identical physical dimensions, thermal characteristics, and packaging standards within the DO-5 outline, differing primarily in their voltage ratings.

Single Diodes Replacement Considerations

Direct substitutes include other 1N1184A variants from different manufacturers that meet the same DO-5 mechanical and electrical specifications. Verify pinout compatibility and thermal performance equivalence before substitution.
