1N1188AR

Single Diodes Overview

The GeneSiC Semiconductor 1N1188AR 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 400 V and a continuous forward current rating of 40 A. The device exhibits a maximum forward voltage of 1.1 V at 40 A and a thermal resistance from junction to case of 1.25 °C/W. Operating temperatures range from -55 °C to 150 °C, with storage capabilities within the same limits.

Single Diodes Feature Summary

• High surge capability for handling transient currents
• Reverse polarity configuration where the stud serves as the anode
• Not sensitive to electrostatic discharge

Single Diodes Applications

• General purpose rectification
• Power supply circuits
• Industrial control systems

Single Diodes Procurement Notes

Verify the specific ordering suffix against manufacturer documentation to confirm terminal configuration. Ensure the procurement specification matches the required reverse polarity variant where the stud functions as the anode rather than the cathode. Confirm compliance requirements and packaging details directly with authorized distributors or the manufacturer prior to purchase.

Single Diodes Selection Notes

Select this component when a 400 V blocking voltage and 40 A continuous current are required in a stud-mount form factor. Consider the 1.25 °C/W thermal resistance for heatsink design calculations. Verify that the reverse polarity orientation aligns with the circuit board layout, as the stud acts as the anode for this specific suffix.

Single Diodes Part Context

This device belongs to the 1N1183A through 1N1190AR series of silicon standard recovery diodes manufactured by GeneSiC Semiconductor. The series offers various voltage ratings from 50 V to 600 V while maintaining a consistent 40 A current capacity and DO-5 package style across all variants.

Single Diodes Replacement Considerations

Compatible substitutes include other 1N1188A variants from different manufacturers such as Digitron, provided they match the 400 V rating, 40 A current, and DO-5 package dimensions. Verify electrical characteristics and pinout compatibility before substitution.

Single Diodes FAQ
