1N1188

Single Diodes Overview

The GeneSiC Semiconductor 1N1188 is a silicon standard recovery rectifier diode housed in a DO-5 (DO-203AB) stud mount package. It features a maximum repetitive peak reverse voltage of 400 V and a continuous forward current rating of 35 A. The device exhibits a maximum forward voltage of 1.2 V at the rated current and supports a surge non-repetitive forward current of 595 A under specified conditions. Operating junction temperatures range from -55 °C to 150 °C, with a thermal resistance from junction to case of 0.25 °C/W.

Single Diodes Feature Summary

• High surge capability for handling transient current loads
• Standard polarity configuration with the stud serving as the cathode terminal

Single Diodes Applications

• Industrial power supply rectification
• Battery charging systems
• General-purpose DC power conversion

Single Diodes Procurement Notes

Verify that the specific unit matches the standard polarity designation where the stud functions as the cathode. Confirm the package type corresponds to the DO-5 mechanical dimensions and mounting requirements. Ensure the selected component meets the required thermal management specifications for the intended operating environment.

Single Diodes Selection Notes

Select this component when a robust standard recovery diode is required for medium-power applications. The 400 V rating suits general AC-to-DC conversion tasks. Consider the stud mount style for efficient heat dissipation through direct chassis or heatsink attachment without additional insulators.

Single Diodes Part Context

This part belongs to the 1N1188 through 1N1190R series of silicon standard recovery diodes manufactured by GeneSiC Semiconductor. The series offers varying reverse voltage ratings while maintaining consistent current capabilities and physical packaging standards for interchangeability within similar design constraints.

Single Diodes Replacement Considerations

Cross-reference with other 1N1188 variants from different manufacturers ensuring identical 400 V reverse voltage, 35 A current rating, and DO-5 package compatibility.
