1N4001W

Single Diodes Overview

The 1N4001W is a surface mount general-purpose silicon rectifier diode manufactured by Shenzhen SLKORMicro Semicon Co., Ltd. It utilizes the SOD-123FL thin package, facilitating automated pick-and-place assembly. The device features a maximum repetitive peak reverse voltage of 50V and a DC blocking voltage of 50V. It supports an RMS voltage of 35V and provides a maximum average forward rectified current of 1A. At a test current of 1A, the typical forward voltage drop is 1.1V. The component withstands an 8.3ms single half-sine-wave surge current of 30A. Electrical characteristics include a typical junction capacitance of 8pF and a junction-to-case thermal resistance of 90°C/W. Reverse leakage current is specified at less than 5μA at 25°C and less than 50μA at 125°C. The operating and storage temperature range spans from -55°C to +150°C.

Single Diodes Feature Summary

Single Diodes Procurement Notes

Verify the specific manufacturer designation when sourcing this component, as the 1N4001 series is produced by multiple vendors including Rectron and others. Confirm that the SOD-123FL package variant matches your board layout requirements. Ensure the supplier provides official datasheets confirming the 50V reverse voltage rating and 1A current handling capabilities before finalizing procurement decisions.

Single Diodes Selection Notes

Select this component for applications requiring surface mount technology with space constraints due to its thin profile. It serves as a direct functional replacement for through-hole 1N4001 diodes where PCB real estate is limited. Consider the 1.1V forward voltage drop and 30A surge rating when designing circuits with high inrush currents or significant transient loads.

Single Diodes Part Context

This part belongs to the broader family of general-purpose silicon rectifiers commonly used in low-voltage power conversion. While the 1N4001 series typically denotes through-hole DO-41 packages, the 'W' suffix indicates a surface mount variant. This specific model addresses modern manufacturing needs for compact electronic assemblies while maintaining standard electrical ratings found in legacy axial components.

Single Diodes Replacement Considerations

Equivalent surface mount parts include the 1N4001S or 1N4001G in compatible packages. Verify pinout compatibility and thermal dissipation limits when substituting across different manufacturers.
