Single Diodes Procurement Notes

Verify the manufacturer designation carefully, as historical production of this part number has involved multiple entities including Microsemi Corporation. Confirm that the specific unit received matches the required electrical specifications and physical package dimensions. Ensure compatibility with existing thermal interface materials and mounting hardware before integration into final assemblies to prevent performance discrepancies.

Single Diodes Selection Notes

Select this component when applications demand a 100 A current capacity with a 150 V voltage rating in a robust stud-mount form factor. The DO-205AA package facilitates direct heatsink attachment for efficient thermal dissipation. Consider the 1.2 V forward voltage drop for efficiency calculations and verify that the 1600 A surge rating meets transient protection requirements within the target circuit design constraints.

Single Diodes Part Context

This component belongs to the family of standard silicon power rectifiers designed for industrial-grade reliability. Originally associated with Microsemi Corporation, the part is now listed under Microchip Technology following corporate acquisitions. The 1N2428 designation follows legacy numbering conventions for general-purpose rectifying diodes, maintaining compatibility with established designs requiring high-current, low-voltage drop performance in fixed mounting configurations.

Single Diodes Replacement Considerations

Cross-reference with other 100 A, 150 V stud-mount rectifiers from various manufacturers. Verify pinout compatibility and thermal resistance values when substituting. Ensure that alternative components meet or exceed the original 1600 A surge current rating and 1.2 V forward voltage specifications to maintain system integrity.
