Single Diodes Procurement Notes

Verify the specific manufacturer source, as this part number is produced by multiple entities including Microchip, Solid State Inc., and others. Confirm RoHS compliance status and exact datasheet revision before procurement, as specifications may vary slightly between original manufacturers and distributors. Ensure the package type matches the required DO-9 form factor for your assembly process.

Single Diodes Selection Notes

Select this component when high average forward current and rugged mechanical mounting are required. Compare the 150V reverse voltage rating against circuit peak inverse voltages. Consider the thermal management requirements associated with the 1.3V forward voltage drop at 275A. Verify that the DO-9 package dimensions fit the available board space or chassis mounting points.

Single Diodes Part Context

This component belongs to the family of general-purpose silicon rectifiers utilizing the DO-9 axial package. Similar parts in this category often share comparable current ratings but differ in voltage ratings or package styles. The 1N2056R specifically addresses applications requiring robust screw-terminal connections rather than surface mount solutions.

Single Diodes Replacement Considerations

Equivalent parts include the 1N2056AR and 1N2056RA from various manufacturers. Verify pinout compatibility and thermal resistance values when substituting. Ensure the replacement device meets the same 275A current and 150V voltage ratings.
