1N1188R

Single Diodes Overview

The GeneSiC Semiconductor 1N1188R is a silicon standard recovery rectifier diode housed in a DO-5 stud mount package. It features a repetitive peak reverse voltage of 400 V and a continuous forward current rating of 35 A. The device exhibits a maximum non-repetitive surge forward current of 595 A under half-sine wave conditions. Electrical characteristics include a forward voltage of 1.2 V at 35 A and a thermal resistance from junction to case of 0.25 °C/W. Operating temperature ranges from -55 °C to +150 °C.

Single Diodes Feature Summary

• High surge capability for handling transient current loads
• Stud base configuration with reversed leads for the 'R' variant
• Not sensitive to electrostatic discharge

Single Diodes Applications

• General purpose rectification circuits
• Power supply designs requiring high surge tolerance
• Industrial equipment utilizing stud-mounted components

Single Diodes Procurement Notes

Verify the specific part number against official datasheets to confirm the reversed lead configuration associated with the suffix. Ensure that the mounting surface preparation aligns with the thermal requirements specified for the DO-5 package. Confirm compliance with relevant environmental standards before finalizing procurement orders.

Single Diodes Selection Notes

Select this component when a robust silicon rectifier with high surge capacity is required in a stud-mount form factor. The reversed lead configuration distinguishes it from standard polarity variants, necessitating careful layout planning. Evaluate thermal management strategies based on the specified junction-to-case thermal resistance for optimal performance.

Single Diodes Part Context

This device belongs to the 1N1188 through 1N1190R series of silicon standard recovery diodes manufactured by GeneSiC Semiconductor. The series offers voltage ratings ranging from 400 V to 600 V within the same physical DO-5 package footprint, allowing for design flexibility while maintaining consistent mechanical and thermal interface specifications across the product line.

Single Diodes Replacement Considerations

Direct substitutes within the same series include the 1N1189R and 1N1190R, which share identical current and thermal ratings but differ in reverse voltage capabilities.
