1N4001

Single Diodes Overview

The onsemi 1N4001 is an axial-lead glass passivated standard recovery rectifier designed for general-purpose low-power applications. It features a maximum average rectified forward current of 1.0 A and a peak repetitive reverse voltage of 50 V. The device operates within a junction temperature range of -65°C to +150°C, with a maximum instantaneous forward voltage drop of 1.1 V at 1.0 A. It supports a non-repetitive peak surge current of 30 A and utilizes a DO-41 plastic molded case.

Single Diodes Procurement Notes

Verify the specific ordering suffix when purchasing. The base part number may be discontinued; confirm availability of Pb-free variants such as the G or RLG suffixes. Ensure the component meets RoHS directives if required. Check datasheet revision dates for updated mechanical dimensions and thermal characteristics before finalizing procurement specifications.

Single Diodes Selection Notes

Select this component for applications requiring a 50 V blocking voltage and 1 A continuous current rating. Consider the thermal resistance values based on the specific mounting method used, such as vector pin or board ground plane configurations. Verify that the operating environment stays within the specified junction temperature limits to ensure reliability.

Single Diodes Part Context

This component belongs to the 1N400x series of axial-lead standard recovery rectifiers manufactured by onsemi. The series includes variants with reverse voltages ranging from 50 V to 1000 V. All devices share similar mechanical characteristics and packaging options, differing primarily in their peak repetitive reverse voltage ratings.

Single Diodes Replacement Considerations

Compatible substitutes include other manufacturers' 1N4001 diodes meeting JEDEC standards. Verify that replacement parts match the 50 V reverse voltage, 1 A forward current, and DO-41 package dimensions. Ensure the alternative component offers comparable surge current handling and thermal performance.
