1N4003-E3/73

Single Diodes Overview

The Vishay 1N4003-E3/73 is a general-purpose plastic rectifier featuring a maximum repetitive peak reverse voltage of 200 V and a maximum average forward rectified current of 1.0 A. It utilizes a DO-41 (DO-204AL) molded epoxy body with matte tin-plated leads for through-hole mounting. 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. It supports a non-repetitive peak forward surge current of 45 A under square wave conditions and operates within a junction temperature range of -50 to +150 °C.

Single Diodes Procurement Notes

Verify the specific ordering suffix against official documentation, as it dictates the delivery mode and base quantity. Confirm that the component meets RoHS compliance standards and passes the JESD 201 class 1A whisker test requirements. Ensure the package code aligns with the required manufacturing process and handling specifications for the intended assembly line.

Single Diodes Selection Notes

Select this component when a standard recovery rectifier with a 200 V reverse voltage rating is required for general-purpose applications. Consider the thermal resistance characteristics and lead length dependencies for derating calculations. Validate suitability for environments requiring operation up to 150 °C junction temperature and verify compatibility with standard through-hole soldering processes.

Single Diodes Part Context

This part belongs to the Vishay 1N400x series of general-purpose plastic rectifiers. The series covers reverse voltage ratings from 50 V to 1000 V while maintaining a consistent 1.0 A average forward current rating across all variants. The E3 suffix indicates RoHS compliance and halogen-free construction, utilizing matte tin-plated terminals suitable for various soldering methods.

Single Diodes Replacement Considerations

Cross-reference with other manufacturers' 1N4003 equivalents or Vishay's GP10 series for similar electrical characteristics. Verify mechanical dimensions and pinout compatibility before substitution.
