1N1185AR

Single Diodes Overview

The 1N1185AR is a standard silicon rectifier diode manufactured by Microchip Technology. It features a maximum average forward rectified current of 40A and a maximum DC reverse voltage (Vr) of 150V. The device utilizes a DO-203AB (DO-5) screw-type package, designed for robust power applications. Key electrical characteristics include a peak repetitive reverse voltage of 50V and a maximum reverse current of 1µA.

Single Diodes Feature Summary

• Standard recovery silicon rectification
• Screw-terminal mounting for secure installation
• High current handling capability

Single Diodes Applications

• Power supply rectification
• General-purpose high-current circuits
• Industrial equipment power stages

Single Diodes Procurement Notes

Verify the specific manufacturer source, as the part is associated with both Microsemi and Microchip Technology due to corporate acquisition history. Confirm RoHS compliance status, as listings indicate non-compliance. Ensure the DO-203AB package and screw-mount configuration match your mechanical design requirements before ordering.

Single Diodes Selection Notes

Select this component when a 40A continuous current rating and 150V reverse voltage blocking are required in a screw-mountable package. Consider the standard recovery time for general rectification tasks rather than high-speed switching applications. Verify thermal management needs for the DO-203AB housing under full load conditions.

Single Diodes Part Context

This component belongs to the standard power rectifier category, historically significant in industrial electronics. The 1N1185AR variant specifically addresses high-current needs using a rugged axial leaded package with a mounting stud. Its specifications align with legacy power conversion standards still used in heavy-duty machinery.

Single Diodes Replacement Considerations

Check for equivalents from other manufacturers offering identical 40A/150V ratings in DO-203AB packages. Ensure any substitute maintains the same screw-mount interface and electrical parameters. Verify availability as the original part may be discontinued.
