1N1190A

Single Diodes Overview

The GeneSiC Semiconductor 1N1190A is a silicon standard recovery rectifier diode housed in a DO-5 (DO-203AB) stud package. It features a maximum repetitive peak reverse voltage of 600 V and a continuous forward current rating of 40 A. The device exhibits a typical forward voltage drop of 1.1 V at 40 A and supports a surge non-repetitive forward current of 800 A for half-sine wave pulses. Thermal resistance from junction to case is specified at 1.25 °C/W, with an operating temperature range spanning -55 °C to +150 °C.

Single Diodes Feature Summary

• Battery charging systems

Single Diodes Procurement Notes

Verify the specific suffix designation against official documentation to confirm terminal polarity. Standard versions utilize a cathode stud, while reverse polarity variants feature an anode stud. Confirm RoHS compliance status as manufacturing specifications may vary by production batch and region. Ensure thermal interface materials are compatible with the stud base for optimal heat dissipation during operation.

Single Diodes Selection Notes

Select this component when a 600 V blocking voltage is required alongside a 40 A continuous current capacity. The DO-5 package facilitates efficient thermal management through direct chassis mounting. Consider the 1.25 °C/W junction-to-case thermal resistance for heatsink calculations. Verify that the application environment remains within the specified -55 °C to +150 °C operating temperature limits.

Single Diodes Part Context

This part belongs to the 1N1183A through 1N1190AR series of silicon standard recovery diodes manufactured by GeneSiC Semiconductor. The series offers various voltage ratings ranging from 50 V to 600 V while maintaining a consistent 40 A current rating across all variants. All members share identical physical dimensions and thermal characteristics within the DO-5 package format.

Single Diodes Replacement Considerations

Cross-reference with other manufacturers offering DO-5 stud rectifiers rated for 600 V and 40 A. Verify that substitute parts match the 1.25 °C/W thermal resistance and 1.1 V forward voltage specifications. Ensure mechanical compatibility with existing mounting hardware and verify electrical parameters align with circuit requirements.
