1N3209

Single Diodes Overview

The GeneSiC Semiconductor 1N3209 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 100 V and a continuous forward current rating of 15 A. The device supports an operating temperature range from -55 °C to +150 °C with a thermal resistance junction-to-case of 0.65 °C/W. Standard polarity designates the stud as the cathode, while the reverse polarity variant (1N3209R) designates the stud as the anode.

Single Diodes Feature Summary

• High surge non-repetitive forward current capability for transient load handling
• Robust thermal performance with low junction-to-case thermal resistance
• ESD insensitive construction for simplified handling

Single Diodes Applications

• General purpose power supply rectification
• Industrial motor drive circuits
• DC power distribution systems

Single Diodes Procurement Notes

Verify the specific polarity requirement before ordering, as the standard 1N3209 has a cathode stud while the 1N3209R has an anode stud. Confirm that the mounting surface can maintain the required thermal interface conditions to ensure the junction temperature remains within the specified operational limits during high-current operation.

Single Diodes Selection Notes

Select this component when a 100 V blocking voltage and 15 A continuous current are required in a stud-mount configuration. Consider the 1N3209R variant if the circuit topology requires the stud terminal to function as the anode rather than the cathode. Ensure the application environment allows for adequate heat dissipation given the 0.65 °C/W thermal resistance specification.

Single Diodes Part Context

This part belongs to the 1N3208 through 1N3211 series of silicon standard recovery diodes. These components share identical physical dimensions and thermal characteristics, differing primarily in their voltage ratings which range from 50 V to 300 V. The series is designed for high-power applications requiring reliable stud-mount solutions.

Single Diodes Replacement Considerations

Cross-reference with other manufacturers offering DO-5 packaged 100 V, 15 A silicon rectifiers. Verify that any substitute matches the 0.65 °C/W thermal resistance and maintains the same stud polarity configuration unless the reverse polarity variant is explicitly intended.
