1N4001RL

Single Diodes Overview

The onsemi 1N4001RL is a glass-passivated standard recovery rectifier diode designed for general-purpose low-power applications. It features an axial lead DO-41 package with a maximum average rectified forward current of 1.0 A and a peak repetitive reverse voltage rating of 50 V. The device supports non-repetitive peak surge currents up to 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 voltage and 25°C.

Single Diodes Feature Summary

• Glass passivation provides protection against mechanical stress and chemical damage
• High surge current capability ensures reliability during transient load conditions
• Low forward voltage drop minimizes power dissipation during conduction

Single Diodes Applications

• General-purpose low-power rectification circuits
• Power supply input stages
• Battery charging systems

Single Diodes Procurement Notes

Verify the specific ordering suffix to confirm packaging configuration, as the RL designation indicates tape and reel shipping. Confirm whether the part number includes the G suffix for Pb-Free compliance or represents legacy material specifications. Cross-reference the manufacturer's discontinuation status before finalizing procurement plans to ensure long-term availability.

Single Diodes Selection Notes

Select this component when a 50 V reverse voltage rating is sufficient for the circuit design. Ensure the application requires standard recovery characteristics rather than fast switching speeds. Verify that the thermal management strategy accommodates the specified junction-to-ambient thermal resistance values under expected operating loads.

Single Diodes Part Context

This device belongs to the 1N400x series of axial-lead rectifiers manufactured by onsemi. The series offers varying reverse voltage ratings from 50 V to 1000 V while maintaining consistent current handling capabilities. The RL variant specifically denotes automated assembly packaging suitable for high-volume surface mount or through-hole production lines.

Single Diodes Replacement Considerations

Substitute with other 1N4001 variants from different manufacturers provided they meet the 50 V reverse voltage and 1.0 A current requirements. Ensure replacement packages match the DO-41 form factor for direct board compatibility.
