1N4003-E3/54

Single Diodes Overview

The Vishay 1N4003-E3/54 is a general-purpose plastic rectifier featuring a 200 V maximum repetitive peak reverse voltage and a 1.0 A average forward rectified current rating. It utilizes a DO-41 (DO-204AL) through-hole package with matte tin-plated leads. The device exhibits a maximum instantaneous forward voltage of 1.1 V at 1.0 A and a maximum DC reverse current of 5.0 μA at rated blocking voltage. Thermal resistance from junction to ambient is typically 50 °C/W, supporting an operating junction temperature range of -50 to +150 °C.

Single Diodes Feature Summary

• Low forward voltage drop for efficient power conversion
• High forward surge capability for transient protection
• Low leakage current characteristics
• Matte tin plated leads compliant with JESD 201 class 1A whisker test

Single Diodes Applications

• General purpose rectification in power supplies
• Inverter circuits
• Converter applications
• Freewheeling diode usage

Single Diodes Procurement Notes

Verify the specific ordering suffix against official Vishay documentation to confirm packaging configuration and compliance status. Confirm that the E3 suffix denotes RoHS compliance and lead finish specifications. Ensure the /54 designation matches the required reel quantity and tape dimensions for automated assembly processes.

Single Diodes Selection Notes

Select this component when a standard recovery rectifier with a 200 V reverse voltage rating is required. The DO-41 package provides robust mechanical stability for through-hole mounting. Consider the thermal resistance and derating curves if operation exceeds standard ambient temperature limits or involves continuous high-current loads.

Single Diodes Part Context

This part belongs to the 1N400x series of general-purpose silicon rectifiers manufactured by Vishay General Semiconductor. The series covers reverse voltages ranging from 50 V to 1000 V, sharing common electrical characteristics such as 1.0 A forward current capacity and standardized DO-41 packaging for interchangeability across various voltage ratings within the family.

Single Diodes Replacement Considerations

Direct substitutes include other manufacturers' 1N4003 variants meeting identical electrical specifications. Verify pinout compatibility and package dimensions before substitution.
