1N4001-B

Single Diodes Overview

The 1N4001-B is a glass passivated junction silicon rectifier manufactured by Diodes Incorporated. It provides an average rectified output current of 1.0 A and a peak repetitive reverse voltage of 50 V. The device features a low forward voltage drop of 1.0 V at 1.0 A and a maximum non-repetitive peak forward surge current rating of 30 A. It operates within a temperature range of -65°C to +150°C and utilizes the DO-41 axial leaded package.

Single Diodes Feature Summary

• Glass passivated die construction for reliable operation
• High current capability with low forward voltage drop
• Surge overload rating up to 30 A peak
• Low reverse leakage current characteristics

Single Diodes Applications

• General purpose rectification in power supplies
• Bridge rectifiers for AC to DC conversion
• Polarity protection circuits
• Free-wheeling diodes in inductive load switching

Single Diodes Procurement Notes

Verify component authenticity through authorized channels, as counterfeit parts may exhibit degraded electrical performance or incorrect markings. Confirm RoHS compliance status and specific packaging requirements prior to ordering. Ensure storage conditions prevent moisture absorption despite Level 1 sensitivity classification. Review datasheet revision history for any parameter updates that may affect design compatibility.

Single Diodes Selection Notes

Select this component for standard frequency applications requiring robust surge handling and simple integration. Consider thermal derating curves when designing for ambient temperatures exceeding 75°C. Evaluate junction capacitance if high-frequency signal integrity is critical. Compare against S1A-S1M series alternatives for potential space-saving surface mount implementations.

Single Diodes Part Context

This part belongs to the widely adopted 1N400x series of general-purpose rectifiers. It serves as the lowest voltage variant (50V) within the family, complementing higher voltage ratings like 1N4002 through 1N4007. The suffix '-B' indicates bulk packaging containing one thousand units per reel, distinct from tape and reel options.

Single Diodes Replacement Considerations

Officially recommended substitutes include the S1A through S1M series for surface mount applications. Cross-manufacturer equivalents such as 1N4001GP or generic 1N4001 variants are parameter-matched but require verification of mechanical dimensions and marking standards.
