1N1204A

Single Diodes Overview

The GeneSiC Semiconductor 1N1204A is a silicon standard recovery rectifier diode housed in a DO-4 (DO-203AA) stud mount package. It supports a repetitive peak reverse voltage of 400 V and a continuous forward current of 12 A. The device features a maximum junction-to-case thermal resistance of 2.00 °C/W and operates within a temperature range of -55 to 150 °C. Electrical characteristics include a forward voltage of 1.1 V at 12 A and a non-repetitive surge forward current capacity of 240 A.

Single Diodes Feature Summary

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

Single Diodes Applications

• General purpose rectification
• Power supply circuits requiring stud mounting
• Industrial equipment power stages

Single Diodes Procurement Notes

Verify the specific datasheet version and manufacturer documentation to confirm electrical parameters and mechanical dimensions. Ensure the ordering suffix matches the required polarity, as the standard configuration designates the stud as the cathode while reverse polarity variants exist. Cross-reference terminal configurations against the target application board layout before finalizing procurement.

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 form factor. The low thermal resistance facilitates efficient heat dissipation through the mounting surface. Consider the standard recovery speed and 1.1 V forward voltage drop for general-purpose applications where ultra-fast switching is not critical.

Single Diodes Part Context

This device belongs to the 1N1199A through 1N1206AR series of silicon standard recovery diodes. All members share identical current ratings, thermal characteristics, and physical package dimensions, 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 1N1200A and 1N1206A, provided the voltage rating aligns with circuit requirements. Verify that replacement parts maintain the DO-4 package and stud polarity configuration to ensure mechanical compatibility.
