1N4001G

Single Diodes Overview

The onsemi 1N4001G is a glass-passivated standard recovery rectifier featuring an axial-lead DO-41 package. It provides a peak repetitive reverse voltage of 50 V and supports an average rectified forward current of 1.0 A at 75°C ambient temperature. The device exhibits a maximum instantaneous forward voltage drop of 1.1 V at 1.0 A and 25°C junction temperature, with a non-repetitive peak surge current rating of 30 A for one cycle. Operating temperatures range from -65°C to +150°C.

Single Diodes Feature Summary

• Glass passivation protects the silicon junction against mechanical stress and environmental variations.
• Plastic epoxy case offers corrosion resistance and meets UL94V-0 flammability ratings.
• Standard recovery characteristics suitable for general-purpose low-power applications.

Single Diodes Applications

• General-purpose low-power rectification
• AC-to-DC power supply circuits
• Freewheeling diode configurations

Single Diodes Procurement Notes

Verify the specific ordering suffix to confirm packaging format. Standard units ship in bags of 1000. Tape and reel options require an RL suffix, while fan-fold packaging requires an FF suffix. Confirm Pb-free status through the /C0071 marking or G suffix if required by assembly specifications.

Single Diodes Selection Notes

Select this component for circuits requiring 50 V blocking capability and 1 A continuous current handling. Ensure thermal management aligns with the specified junction-to-ambient resistance values for the chosen mounting method. Verify that the application does not exceed the 30 A non-repetitive surge limit during turn-on events.

Single Diodes Part Context

This part belongs to the 1N400x series of axial-lead rectifiers, differentiated by their reverse voltage ratings ranging from 50 V to 1000 V. The 1N4001G specifically denotes the 50 V variant within this family, sharing identical current ratings and physical dimensions with higher voltage counterparts like the 1N4002G through 1N4007G.

Single Diodes Replacement Considerations

Direct substitutes include other manufacturers' 1N4001 variants meeting JEDEC DO-41 standards. Cross-reference electrical parameters such as forward voltage and reverse leakage to ensure compatibility with existing circuit designs.
