1N1204AR

Single Diodes Overview

The GeneSiC Semiconductor 1N1204AR is a silicon standard recovery rectifier diode rated for a repetitive peak reverse voltage of 400 V and a continuous forward current of 12 A. It utilizes a DO-4 (DO-203AA) stud mount package with the stud configured as the anode, distinguishing it from standard polarity variants. The device supports an operating temperature range from -55 °C to 150 °C and features a junction-to-case thermal resistance of 2.00 °C/W.

Single Diodes Feature Summary

• High surge capability designed to withstand non-repetitive forward currents up to 240 A under specified half-sine wave conditions.

Single Diodes Applications

• General purpose power rectification in industrial equipment
• AC to DC conversion circuits requiring stud mounting
• Power supplies utilizing high-current standard recovery diodes

Single Diodes Procurement Notes

Verify the 'R' suffix indicates reverse polarity where the stud functions as the anode rather than the cathode. Confirm the manufacturer designation aligns with GeneSiC Semiconductor specifications. Ensure the DO-4 package dimensions match the required mechanical interface for the intended heatsink or chassis mounting application.

Single Diodes Selection Notes

Select this component when a 400 V blocking voltage and 12 A continuous current rating are required in a stud-mount configuration. The reverse polarity variant is necessary if the circuit design mandates the stud terminal serve as the positive input connection. Evaluate thermal management requirements based on the 2.00 °C/W junction-to-case resistance.

Single Diodes Part Context

This part belongs to the 1N1199A through 1N1206AR series of silicon standard recovery diodes. All members share identical electrical ratings for current and thermal characteristics, differing only in their maximum repetitive peak reverse voltage ratings ranging from 50 V to 600 V.

Single Diodes Replacement Considerations

Cross-reference with other manufacturers offering 12 A, 400 V stud-mount diodes in the DO-4 package. Verify that substitute parts accommodate the specific reverse polarity requirement where the stud acts as the anode.
