1N1183A

Single Diodes Overview

The GeneSiC Semiconductor 1N1183A 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 50 V and supports a continuous forward current of 40 A. The device exhibits a forward voltage of 1.1 V at 40 A and a non-repetitive surge current capability of 800 A. Operating temperatures range from -55 °C to 150 °C, with a thermal resistance junction-to-case of 1.25 °C/W.

Single Diodes Feature Summary

• High surge current capability for robust transient handling
• Standard polarity configuration with the stud serving as the cathode
• Not sensitive to electrostatic discharge

Single Diodes Applications

• General purpose power rectification
• High reliability industrial applications
• Aerospace systems requiring high surge tolerance

Single Diodes Procurement Notes

Verify that the specific part number matches the required voltage rating, as the series includes variants up to 600 V. Confirm the suffix designation to ensure correct terminal polarity; the standard 'A' variant has the stud as the cathode, while the '(R)' suffix indicates reverse polarity where the stud is the anode. Ensure mounting hardware compatibility with the 1/4–28 UNF thread specification.

Single Diodes Selection Notes

Select this component when a 50 V blocking voltage and 40 A continuous current are required in a stud-mount form factor. The low thermal resistance facilitates efficient heat dissipation for high-power designs. Consider the reverse polarity option if system grounding requires the stud to function as the anode rather than the cathode.

Single Diodes Part Context

This device belongs to the 1N1183A through 1N1190AR series of silicon standard recovery diodes. All members of this family share identical electrical characteristics regarding current capacity and thermal performance, differing only in their maximum repetitive peak reverse voltage ratings which range from 50 V to 600 V.

Single Diodes Replacement Considerations

Direct substitutes within the same series include the 1N1184A, 1N1188A, and 1N1190A, provided the circuit voltage requirements align with their respective higher reverse voltage ratings. Verify mechanical fitment for the DO-5 package before substitution.
