Single Diodes Procurement Notes

Verify the End of Life status before procurement. The manufacturer issued a Product Discontinuation Notice indicating this part is discontinued. Confirm availability of final stock or transition to the designated replacement part number. Contact engineering support for alternate sourcing assistance if necessary.

Single Diodes Selection Notes

Select this component only if legacy compatibility with the 1N4003 specification is required. Note that the 'BK' suffix indicates bulk packaging. Evaluate the recommended replacement part for equivalent electrical parameters and mechanical fit in existing designs.

Single Diodes Part Context

This diode is part of the 1N4001 series manufactured by Central Semiconductor Corp. The series includes variants with different reverse voltage ratings ranging from 50V to 1000V. All parts share the same 1A forward current rating and DO-41 package style, differing primarily in their blocking voltage capabilities.

Single Diodes Replacement Considerations

The official replacement for the 1N4003 BK is the 1N4007 BK. Verify that the higher reverse voltage rating of the replacement does not conflict with design constraints.
