1N4003

Single Diodes Overview

The MCC 1N4003 is a silicon rectifier diode designed for general-purpose applications. It features a maximum average forward rectified current of 1 A and a peak repetitive reverse voltage rating of 200 V. The device utilizes a glass passivated junction construction to ensure high reliability under various operating conditions. It is housed in the DO-41 axial leaded package, suitable for through-hole mounting on printed circuit boards. The component supports a maximum non-repetitive peak forward surge current of 30 A and operates within a temperature range from -65 °C to 175 °C.

Single Diodes Procurement Notes

Verify the specific manufacturer designation when sourcing, as multiple vendors produce components with this part number. Confirm RoHS compliance status if required by project specifications, noting that older or specific variants may differ. Ensure the package type matches the intended PCB footprint requirements before finalizing procurement decisions.

Single Diodes Selection Notes

Select this component for standard low-frequency rectification tasks requiring 1 A continuous current handling. Consider the 200 V reverse voltage rating to ensure adequate margin against peak line voltages. Evaluate thermal management needs based on the specified junction temperature limits and ambient operating environment constraints.

Single Diodes Part Context

This component belongs to the widely recognized 1N400x series of silicon rectifiers. These parts are industry standards for basic AC-to-DC conversion and signal isolation. The 1N4003 variant specifically provides a 200 V blocking voltage, distinguishing it from lower-voltage siblings like the 1N4001 or higher-voltage counterparts like the 1N4004.

Single Diodes Replacement Considerations

Direct functional substitutes include other manufacturers' 1N4003 diodes such as Vishay 1N4003E-E3/54 or onsemi 1N4003. Verify pinout compatibility and physical dimensions to ensure interchangeability in existing assemblies without modifying the PCB layout.
