1N4001G-K

Single Diodes Overview

The 1N4001G-K is a general-purpose silicon rectifier diode manufactured by Taiwan Semiconductor Corporation. It features a glass passivated junction and is housed in a DO-41 axial leaded package. The device is rated for a maximum repetitive peak reverse voltage of 50V and an average forward rectified current of 1A at 75°C. Key electrical characteristics include a maximum DC blocking voltage of 50V, a typical forward voltage drop of 1.1V at 1A, and a peak non-repetitive surge current capability of 30A. The component supports a wide operating temperature range from -65°C to +150°C.

Single Diodes Feature Summary

• Glass passivated chip junction provides high reliability and stability against mechanical stress.
• Plastic molded case meets UL flammability classification 94V-0.
• Terminals are plated axial leads that are solderable per MIL-STD-750 standards.

Single Diodes Applications

• General purpose rectification in power supply circuits
• Reverse polarity protection in electronic devices
• Freewheeling applications in inductive load switching

Single Diodes Procurement Notes

Verify the specific suffix K against the manufacturer's official datasheet to confirm it denotes a standard tape-and-reel packaging format or specific marking code rather than a functional deviation. Ensure compliance with RoHS directives and confirm the absence of halogenated materials if required by your assembly specifications. Cross-reference the part number with authorized distributors to validate authenticity and traceability.

Single Diodes Selection Notes

Select this component when a robust, cost-effective solution for low-frequency AC-to-DC conversion is required. The DO-41 package offers reliable through-hole mounting for prototyping and industrial equipment. Consider the 1A current rating and 50V breakdown voltage to ensure adequate headroom for the target circuit's peak inverse voltage and continuous load requirements.

Single Diodes Part Context

This part belongs to the widely adopted 1N400x series of silicon rectifiers, which serves as a standard industry reference for general-purpose power applications. The 'G' suffix typically indicates a glass passivated junction construction, distinguishing it from plastic-only variants. This series is characterized by its simplicity, high surge current handling, and compatibility with standard manufacturing processes.

Single Diodes Replacement Considerations

Direct pin-compatible substitutes include the 1N4001 from other manufacturers such as Vishay, Diotec, or LRC. Verify that alternative sources maintain the same DO-41 package dimensions and thermal characteristics. Ensure that any replacement part meets the identical 50V reverse voltage and 1A current ratings for safe integration.
