1N4003

Single Diodes Overview

The Diotec Semiconductor 1N4003 is a standard recovery rectifier diode housed in the DO-41 axial leaded package. It features a maximum repetitive peak reverse voltage of 200 V and an average forward rectified current rating of 1 A. The device exhibits a maximum forward voltage drop of 1.1 V at rated current and a low reverse leakage current of 5 µA. It supports a maximum non-repetitive peak forward surge current of 30 A and operates within a junction temperature range of -55 °C to +150 °C.

Single Diodes Procurement Notes

Verify the specific manufacturer suffix or ordering code, as the base part number 1N4003 is produced by multiple vendors including Diotec, onsemi, and MCC. Confirm RoHS compliance status and packaging format (bulk vs. tape and reel) directly with the supplier. Ensure the component matches the required electrical specifications for your design before procurement.

Single Diodes Selection Notes

Select this component for applications requiring reliable standard recovery performance at 1 A. Consider the DO-41 package size for through-hole mounting constraints. Evaluate thermal management requirements given the 150 °C junction limit. Compare alternative manufacturers if supply chain diversification is necessary, ensuring pinout and electrical ratings remain compatible.

Single Diodes Part Context

The 1N4003 belongs to the widely recognized 1N400x series of silicon rectifier diodes. This series is a industry-standard solution for low-frequency power conversion tasks. Diotec Semiconductor manufactures this variant to meet established JEDEC mechanical outlines while providing consistent electrical performance across production batches.

Single Diodes Replacement Considerations

Direct substitutes include 1N4003G, 1N4003-TP, and 1N4003M02. Verify that replacement parts maintain identical voltage, current, and package specifications.
