1N4001G R1G

Single Diodes Overview

The Taiwan Semiconductor 1N4001G R1G is a standard silicon rectifier diode housed in the DO-204AL (DO-41) axial leaded package. It features a glass passivated chip junction and supports a maximum average forward rectified current of 1 A with a repetitive peak reverse voltage of 50 V. The device withstands a non-repetitive peak forward surge current of 30 A under an 8.3 ms single half-sine wave condition. Electrical characteristics include a maximum forward voltage of 1 V at 1 A, a maximum reverse leakage current of 5 µA at rated voltage and 25°C, and a typical junction capacitance of 10 pF. The component operates within a junction temperature range of -55°C to +150°C.

Single Diodes Feature Summary

• Glass passivated chip junction construction for enhanced reliability
• High surge current capability supporting transient load conditions
• Low forward voltage drop contributing to high efficiency and low power loss
• Halogen-free molding compound compliant with IEC 61249-2-21 standards

Single Diodes Applications

• DC to DC converter circuits
• Switching mode converters and inverters
• General purpose rectification tasks

Single Diodes Procurement Notes

Verify that the specific ordering code matches the required packaging format, as the manufacturer offers variations such as tape and reel or ammo box quantities. Confirm whether the application requires AEC-Q101 automotive qualification, which necessitates selecting parts with the designated suffix rather than the standard commercial grade version. Ensure compliance with RoHS directives and halogen-free requirements during the sourcing process.

Single Diodes Selection Notes

Select this component for general-purpose applications requiring robust 1 A rectification with a 50 V blocking capability. The DO-204AL package provides reliable through-hole mounting suitable for various industrial and consumer electronics designs. Consider the thermal resistance and derating curves when designing for high ambient temperatures or continuous high-current loads to ensure long-term operational stability.

Single Diodes Part Context

This part belongs to the 1N4001G series, which includes variants ranging from 50 V to 1000 V reverse voltage ratings. All members share identical mechanical dimensions and current handling capabilities, differing only in their breakdown voltage specifications. The series utilizes a standardized glass passivation process to maintain consistent performance across the entire voltage range.

Single Diodes Replacement Considerations

Direct replacements include other manufacturers' 1N4001 diodes in the DO-41 package. Verify that substitute components meet the same 1 A forward current and 50 V reverse voltage ratings. Ensure the alternative parts also feature glass passivation if environmental reliability is a priority.

Single Diodes FAQ

Does the 1N4001G R1G have automotive qualification?

Standard versions are not AEC-Q101 qualified. Automotive-grade versions are available but require the 'H' suffix in the ordering code.

What is the maximum operating junction temperature?

The maximum junction temperature is +150°C.
