1N3209R

Single Diodes Overview

The GeneSiC Semiconductor 1N3209R 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 supports a continuous forward current of 15 A. The device operates within a junction temperature range of -55 °C to +150 °C, with a maximum thermal resistance from junction to case of 0.65 °C/W. The 'R' suffix indicates reverse polarity configuration where the stud serves as the anode.

Single Diodes Feature Summary

Single Diodes Procurement Notes

Verify the specific manufacturer source when ordering, as this part number is widely distributed across multiple semiconductor vendors including Infineon, Vishay, and Microsemi. Confirm that the reverse polarity designation matches your circuit requirements, as standard versions utilize the stud as the cathode. Ensure the supplier provides official datasheets confirming the 100 V rating and DO-5 package dimensions before finalizing procurement.

Single Diodes Selection Notes

Select this component for applications requiring robust standard recovery characteristics in a high-current stud-mount form factor. The 15 A continuous rating and 100 V blocking voltage make it suitable for low-voltage, high-current DC power systems. Consider the thermal resistance of 0.65 °C/W when designing heatsinking solutions to maintain junction temperatures within the specified operating range under full load conditions.

Single Diodes Part Context

This device belongs to the 1N3208 through 1N3211 series of silicon standard recovery diodes. The series offers various voltage ratings from 50 V to 300 V while maintaining a consistent 15 A forward current capacity. The 1N3209R specifically addresses the need for a 100 V rated device with reversed terminal polarity, providing design flexibility for specific grounding or connection topologies in power electronics.

Single Diodes Replacement Considerations

Equivalent parts include the 1N3209 without the R suffix if standard polarity is acceptable. Cross-reference with other manufacturers' 1N3209 equivalents such as those from Vishay or Infineon, ensuring the DO-5 package and electrical ratings match exactly.
