1N4001RLG

Single Diodes Overview

The onsemi 1N4001RLG is a glass-passivated standard recovery rectifier featuring an axial-lead DO-41 package. It provides a maximum repetitive reverse voltage of 50 V and supports a continuous average forward current of 1.0 A. The device withstands a non-repetitive peak surge current of 30 A for one cycle at 60 Hz. 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. Operating junction temperatures range from -65°C to +150°C.

Single Diodes Feature Summary

• Glass passivation protects the silicon junction against mechanical stress and ensures stable electrical performance.
• Axial lead configuration facilitates through-hole mounting in general-purpose low-power applications.
• Lead-free construction complies with environmental directives.

Single Diodes Applications

• General-purpose rectification in low-power electronic circuits
• AC to DC conversion in power supply inputs
• Protection against reverse polarity in DC circuits

Single Diodes Procurement Notes

Verify that the ordering suffix 'RLG' corresponds to the tape and reel packaging format containing 5000 units per reel, as specified in the official datasheet. Confirm the component is marked with the Pb-Free indicator '/C0109A'. Ensure the procurement source references the specific document number 1N4001/D to validate the manufacturer's specifications and revision status.

Single Diodes Selection Notes

Select this component when a 50 V blocking capability is required for single-phase resistive loads operating at 60 Hz. The 1.0 A average forward current rating defines its suitability for low-power applications. Verify that the thermal resistance requirements align with the intended mounting method, as junction-to-ambient resistance varies based on lead length and board ground plane presence.

Single Diodes Part Context

This part belongs to the 1N400x series of axial-lead standard recovery rectifiers manufactured by onsemi. The series covers reverse voltages from 50 V to 1000 V, sharing identical mechanical dimensions and forward current ratings while differing in breakdown voltage specifications. The 'RLG' designation specifically identifies the reel-packaged, lead-free variant within this family.

Single Diodes Replacement Considerations

Cross-reference with other manufacturers offering the 1N4001 specification in the DO-41 package. Verify that substitute components meet the same 50 V reverse voltage, 1.0 A forward current, and 30 A surge current ratings. Ensure the replacement maintains the glass-passivated junction technology for equivalent reliability.
