1N4003

Single Diodes Overview

The onsemi 1N4003 is a glass-passivated standard recovery rectifier designed for general-purpose low-power applications. It features an axial-lead plastic package (DO-41) with a maximum average forward rectified current of 1.0 A and a peak repetitive reverse voltage rating of 200 V. The device supports a non-repetitive peak surge current of 30 A and operates within a junction temperature range of -65°C to +150°C.

Single Diodes Feature Summary

• Glass passivation provides protection against mechanical stress and moisture
• High surge current capability for transient load handling
• Low forward voltage drop for improved efficiency
• Lead-free packaging available

Single Diodes Applications

• General-purpose rectification in low-power circuits
• Power supply input stages
• DC output rectification

Single Diodes Procurement Notes

Verify the specific ordering suffix to confirm packaging format, as the base part number may be discontinued while Pb-free variants remain active. Confirm availability through official onsemi channels or authorized distributors, as shipping configurations vary by suffix code.

Single Diodes Selection Notes

Select this component for applications requiring a 200 V reverse voltage rating and 1 A continuous current capacity. Ensure thermal management aligns with the specified junction-to-ambient resistance values for the intended mounting method.

Single Diodes Part Context

This device belongs to the 1N400x series of axial-lead rectifiers manufactured by onsemi. The series includes variants with different reverse voltage ratings ranging from 50 V to 1000 V, sharing identical physical dimensions and current handling characteristics.

Single Diodes Replacement Considerations

Compatible substitutes include other manufacturers' 1N4003 diodes meeting JEDEC DO-41 specifications. Verify that replacement parts match the 200 V reverse voltage and 1 A forward current ratings.
