1N1189R

Single Diodes Overview

The GeneSiC Semiconductor 1N1189R is a silicon standard recovery rectifier diode housed in the DO-5 (DO-203AB) stud package. It features a maximum repetitive peak reverse voltage of 600 V and a continuous forward current rating of 35 A at Tj = 25 °C. The device supports a surge non-repetitive forward current of 595 A under half-sine wave conditions. Operating temperature ranges from -55 °C to 150 °C, with storage temperatures spanning -55 °C to 150 °C. The 'R' suffix indicates reversed polarity where the stud functions as the anode.

Single Diodes Feature Summary

• High surge current capability for robust transient handling
• Not sensitive to electrostatic discharge
• Stud base configuration for efficient thermal management

Single Diodes Applications

• General purpose power rectification
• Industrial power supplies
• High reliability equipment requiring high surge tolerance

Single Diodes Procurement Notes

Verify the specific manufacturer source when ordering, as this component family is produced by multiple vendors including GeneSiC, Microchip, and Vishay. Confirm that the 'R' designation matches the required reversed polarity configuration where the stud serves as the anode. Ensure the procurement documentation explicitly states compliance with the DO-5 mechanical dimensions and terminal configurations provided in the datasheet.

Single Diodes Selection Notes

Select this component for applications requiring a 600 V blocking voltage and 35 A continuous current capacity. The DO-5 stud package facilitates direct mounting to heatsinks for effective thermal dissipation. Consider the reversed polarity configuration if the circuit design requires the stud terminal to function as the anode rather than the cathode. Verify that the operating junction temperature remains within the specified -55 °C to 150 °C range during operation.

Single Diodes Part Context

This part belongs to the 1N1188 through 1N1190R series of silicon standard recovery diodes. These components are designed for high-power applications utilizing the DO-5 stud package. The series offers various voltage ratings ranging from 400 V to 600 V while maintaining consistent current handling capabilities across the lineup.

Single Diodes Replacement Considerations

Compatible substitutes include the 1N1189 and 1N1190 variants within the same series, provided the voltage ratings meet the application requirements. Cross-manufacturer equivalents such as those from Microchip or Vishay may be used if they adhere to the same JEDEC DO-5 package specifications and electrical characteristics.
