• Robust construction utilizing a metal stud mount package for thermal management
• Designed for general-purpose rectification tasks

Single Diodes Applications

• General purpose rectification circuits
• Industrial power conversion systems
• High current DC power supplies

Single Diodes Procurement Notes

Verify the manufacturer designation carefully, as the 1N4055R part number is historically associated with Powerex Inc. Confirm that the specific Microchip Technology variant matches the required electrical specifications and physical dimensions before integration. Ensure the stud mount configuration aligns with the intended heatsink or chassis mounting requirements for proper thermal dissipation.

Single Diodes Selection Notes

Select this component when high average current ratings near 275 A are required alongside a 900 V reverse voltage blocking capability. The stud mount form factor is essential for applications necessitating direct chassis mounting for efficient heat transfer. Evaluate the thermal resistance characteristics against the system's cooling infrastructure to ensure reliable operation at elevated junction temperatures up to 190 °C.

Single Diodes Part Context

This component belongs to the family of high-power silicon rectifier diodes designed for industrial and heavy-duty electronics. Unlike low-power signal diodes, these devices prioritize current carrying capacity and ruggedness over speed. The stud mount style distinguishes it from axial or surface-mount alternatives, indicating its use in fixed, high-power installations rather than dense PCB layouts.

Single Diodes Replacement Considerations

Cross-reference with other 900V 275A stud-mount rectifiers. Verify pinout compatibility and thermal interface requirements when substituting.
