Procurement Notes

Verify the specific manufacturer designation when sourcing, as the 1N5401K part number is utilized by multiple semiconductor producers including Diotec. Confirm that the received component matches the DO-204AC package dimensions and lead configuration. Ensure compliance with RoHS3 regulations if required by your assembly specifications. Cross-reference datasheets to confirm electrical parameters align with your circuit requirements before finalizing procurement.

Selection Notes

Select this component for applications requiring reliable 3 A rectification at 100 V reverse voltage. The DO-204AC package provides adequate heat dissipation for moderate power levels. Consider the 1.5 µs reverse recovery time when evaluating suitability for higher frequency switching applications. Verify that the 1.1 V forward voltage drop meets the efficiency targets of your specific power design constraints.

Part Context

This component belongs to the widely recognized 1N54xx series of silicon rectifiers. These devices are standardized across the industry for basic AC-to-DC conversion tasks. The 'K' suffix typically denotes specific packaging or tape-and-reel variations depending on the original equipment manufacturer. The series remains a fundamental building block in legacy and modern electronic designs requiring robust, cost-effective power handling.

Replacement Considerations

Compatible substitutes include the 1N5400, 1N5402, and 1N5403 from various manufacturers. These parts share identical pinouts and similar electrical characteristics within the same voltage and current ratings. Verify package compatibility and reverse voltage tolerance when substituting to ensure circuit integrity.
