1N4001-T

Single Diodes Overview

The Lumimax Optoelectronic Technology 1N4001-T is a general-purpose silicon rectifier diode housed in a DO-41 (DO204AL) axial leaded package. It features a maximum repetitive peak reverse voltage of 50 V and a maximum average forward rectified current of 1.0 A at 75°C ambient temperature. The device supports a peak forward surge current of 30 A under single half-sine-wave conditions. Electrical characteristics include a maximum instantaneous forward voltage of 1.1 V, a maximum DC reverse current of 50 μA at rated blocking voltage, and a typical junction capacitance of 15 pF. The component operates within a temperature range of -50°C to +150°C.

Single Diodes Feature Summary

• Low forward voltage drop for efficient power conversion
• High forward surge current capability for transient protection
• Guaranteed high-temperature soldering performance up to 260°C
• Compliant with RoHS and REACH environmental directives

Single Diodes Applications

• General purpose rectification in AC-to-DC power supplies
• Polarity protection circuits
• Freewheeling diodes in inductive load switching

Single Diodes Procurement Notes

Verify the manufacturer designation matches Lumimax Optoelectronic Technology rather than other vendors using identical part numbers. Confirm the suffix 'T' corresponds to the specific tape-and-reel or bulk packaging configuration defined in the official datasheet. Ensure compliance requirements such as UL 94V-0 flammability rating are explicitly stated for the intended application environment.

Single Diodes Selection Notes

Select this component when a standard 1A rectifier with a 50V reverse voltage rating is required. The DO-41 package facilitates through-hole mounting on printed circuit boards. Consider the thermal resistance and derating curves if operating near the maximum temperature limits. Verify that the 30A surge current rating meets the peak inrush requirements of the target circuit design.

Single Diodes Part Context

This device belongs to the 1N4001 through 1N4007 series of general-purpose silicon rectifiers. All members share identical forward current and surge ratings but differ in their maximum repetitive peak reverse voltage capabilities. The 1N4001 variant specifically provides the lowest voltage rating within this family, suitable for low-voltage AC line applications.

Single Diodes Replacement Considerations

Cross-reference with other manufacturers offering 1N4001 specifications in DO-41 packages. Verify pinout polarity and mechanical dimensions match the existing footprint. Ensure electrical parameters such as forward voltage and reverse leakage do not exceed original design margins.
