1N4003E-E3/73

Single Diodes Overview

The Vishay 1N4003E-E3/73 is a general-purpose plastic rectifier featuring a DO-41 (DO-204AL) molded epoxy body. It provides a maximum repetitive peak reverse voltage of 200 V and supports a maximum average forward rectified current of 1.0 A at 75 °C with 0.375-inch lead length. 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. Peak forward surge current capability reaches 30 A for an 8.3 ms sine-wave or 45 A for a 1 ms square waveform. Operating junction and storage temperatures range from -50 to +150 °C.

Single Diodes Feature Summary

Single Diodes Procurement Notes

Verify the specific ordering suffix against official documentation, as it dictates packaging format and base quantity. Confirm RoHS compliance status and material categorization requirements prior to procurement. Ensure that terminal plating specifications meet solderability standards required by the assembly process. Validate environmental compliance data such as REACH SVHC declarations before finalizing supply chain agreements.

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 accommodates through-hole mounting configurations suitable for general circuit board layouts. Consider the thermal resistance characteristics and derating curves if operating near maximum temperature limits. Verify compatibility with existing freewheeling or bridge rectifier applications within the target design constraints.

Single Diodes Part Context

This part belongs to the Vishay 1N4001 through 1N4007 series of general-purpose plastic rectifiers. All members share identical electrical parameters except for the maximum repetitive peak reverse voltage, which varies across the series. The E3 suffix indicates RoHS compliance and commercial grade construction. The /73 suffix specifically denotes Ammo pack packaging with a base quantity of 3000 units.

Single Diodes Replacement Considerations

Cross-reference other manufacturers' 1N4003 equivalents to ensure pinout and package dimensions match the DO-41 form factor. Verify that substitute components meet the same 200 V reverse voltage and 1.0 A forward current ratings. Check thermal resistance values to ensure equivalent heat dissipation capabilities in the intended application environment.
