1N4001

Single Diodes Overview

The Diotec Semiconductor 1N4001 is a standard recovery rectifier diode housed in the DO-204AC (DO-41) axial through-hole package. It features a maximum average forward rectified current of 1 A and a repetitive peak reverse voltage of 50 V. The device exhibits a maximum forward voltage of 1.1 V at 1 A, with a typical reverse recovery time of 1500 ns. Peak forward surge current ratings are 30 A for 60 Hz half-sine waves and 27 A for 50 Hz cycles. Junction capacitance is typically 15 pF at 4 V reverse bias.

Single Diodes Procurement Notes

Verify the specific manufacturer part number against official Diotec Semiconductor documentation to confirm exact electrical tolerances and package dimensions. Ensure compliance with RoHS and ELV directives as stated in the datasheet. Confirm that the component meets commercial/industrial grade reliability standards suitable for the intended application environment before finalizing procurement.

Single Diodes Selection Notes

Select this component when a robust, cost-effective solution for low-frequency AC-to-DC conversion or DC polarity blocking is required. The 50 V reverse voltage rating suits lower voltage mains rectification tasks. Consider the thermal resistance characteristics if operating near maximum ambient temperature limits or requiring derating for sustained high-current loads.

Single Diodes Part Context

This component belongs to the widely recognized 1N400x series of standard recovery rectifiers. It shares the same physical footprint and basic operational principles as variants like the 1N4002 through 1N4007, differentiated primarily by their reverse voltage breakdown capabilities. The 1N4001 specifically targets applications requiring a minimum 50 V blocking threshold.

Single Diodes Replacement Considerations

Cross-reference with other manufacturers' 1N4001 equivalents such as Vishay 1N4001GP or Diodes Incorporated 1N4001G-T. Verify that substitute parts maintain identical DO-41 packaging, 1 A current rating, and 50 V reverse voltage specifications to ensure mechanical and electrical compatibility.
