1N4002

Single Diodes Overview

The onsemi 1N4002 is a general-purpose silicon rectifier featuring a maximum average forward rectified current of 1.0 A and a peak repetitive reverse voltage of 100 V. It utilizes an axial-lead glass-passivated standard recovery design housed in a DO-41 (Case 59-10) epoxy molded package. 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. Electrical characteristics include a maximum instantaneous forward voltage drop of 1.1 V at 1.0 A and a maximum reverse current of 10 µA at rated DC blocking voltage.

Single Diodes Feature Summary

• Glass passivation provides environmental protection for the diffused junction.
• Axial lead mounting facilitates through-hole installation with polarity indicated by a cathode band.
• High surge current capability ensures reliability under transient load conditions.

Single Diodes Applications

• General-purpose low-power rectification
• AC to DC conversion circuits
• Power supply input stages

Single Diodes Procurement Notes

Verify the specific ordering suffix when purchasing, as packaging options vary significantly between bulk bags, tape and reel, and fan-fold boxes. Confirm whether the required unit is the Pb-free version or the discontinued legacy variant. Ensure the selected configuration matches the intended assembly method and quantity requirements for production efficiency.

Single Diodes Selection Notes

Select this component for applications requiring a 100 V reverse voltage rating and 1 A continuous forward current. Consider thermal resistance values based on the specific lead length and board mounting geometry used in the design. Verify that the operating environment remains within the specified temperature limits to maintain performance and longevity.

Single Diodes Part Context

This part belongs to the 1N400x series of axial-lead rectifiers, which includes variants ranging from 50 V to 1000 V reverse voltage ratings. All members share identical mechanical dimensions and current handling capabilities, differing only in their breakdown voltage specifications. This family is widely recognized for standard recovery performance in basic power electronics.

Single Diodes Replacement Considerations

Direct substitutes include other manufacturers' 1N4002 diodes meeting JEDEC DO-41 outlines. Cross-reference with 1N4002G or 1N4002RLG equivalents from other suppliers if sourcing constraints exist. Ensure replacement parts match the 100 V reverse voltage and 1 A forward current ratings exactly.
