1N1183

Single Diodes Overview

The GeneSiC Semiconductor 1N1183 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 50 V and a continuous forward current rating of 35 A. The device exhibits a maximum forward voltage of 1.2 V at 35 A and a reverse leakage current of 10 µA at 50 V. It supports a surge non-repetitive forward current of 595 A under half-sine wave conditions. Thermal resistance from junction to case is 0.25 °C/W, with an operating temperature range spanning -55 °C to 150 °C.

Single Diodes Procurement Notes

Verify the specific manufacturer source, as production rights for this part number may have transferred between entities such as Vishay and Microchip. Confirm RoHS compliance status directly with the supplier, as historical data indicates variations across different manufacturing origins. Ensure the package terminal configuration matches the required circuit polarity before integration.

Single Diodes Selection Notes

Select this component for applications requiring robust high-current handling within a compact stud-mount form factor. The low thermal resistance allows effective heat dissipation when mounted to a heatsink. Consider the 50 V reverse voltage limit to ensure adequate margin against line transients in low-voltage DC conversion designs.

Single Diodes Part Context

This device belongs to the 1N1183 through 1N1187R series of silicon standard recovery diodes. The series offers varying reverse voltage ratings from 50 V to 300 V while maintaining a consistent 35 A forward current capacity. These components are designed for high-reliability environments, including aerospace and military specifications, utilizing a rugged DO-5 package.

Single Diodes Replacement Considerations

The 1N1183R serves as the reverse polarity variant within the same series, where the stud functions as the anode instead of the cathode. Other series members like the 1N1184 offer higher voltage ratings but share identical current and thermal characteristics.
