Single Diodes Procurement Notes

Verify the specific suffix 'AT-82' against official Rohm documentation to confirm tape-and-reel packaging specifications and marking codes. Ensure that the procurement source provides valid RoHS compliance data and confirms the component's active status or last-time-buy designation. Cross-reference the manufacturer part number with authorized distributor databases to validate authenticity and traceability before finalizing orders.

Single Diodes Selection Notes

Select this component when a 400 V reverse voltage rating and 1 A continuous current capacity are required for through-hole implementations. The 1N4004AT-82 is suitable for designs prioritizing high junction temperature operation up to 175 °C. Consider the DO-201AD package dimensions for PCB layout constraints and verify that the standard recovery characteristics align with the switching frequency requirements of the target application circuit.

Single Diodes Part Context

This component belongs to the 1N400x series of general-purpose silicon rectifiers produced by Rohm Semiconductor. The series offers various reverse voltage ratings ranging from 50 V to 1000 V while maintaining a consistent 1 A average forward current capability. The 1N4004 variant specifically targets applications requiring a 400 V blocking voltage, providing a balance between cost-effectiveness and performance for industrial and consumer electronics power stages.

Single Diodes Replacement Considerations

Compatible substitutes include the 1N4004 from onsemi and Vishay Semiconductors, provided they meet the same DO-201AD package and electrical specifications. Verify that alternative manufacturers offer equivalent surge current ratings and thermal characteristics to ensure direct functional interchangeability without redesigning the host circuit board.
