1N4004-E3/73

Single Diodes Overview

The Vishay General Semiconductor - Diodes Division 1N4004-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 400 V and supports a maximum average forward rectified current of 1.0 A at an ambient temperature of 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 and 25 °C. Non-repetitive peak forward surge current reaches 30 A for an 8.3 ms single half sine-wave or 45 A for a square waveform at 25 °C. Operating junction and storage temperatures range from -50 to +150 °C.

Single Diodes Procurement Notes

Verify the specific ordering suffix against official documentation, as it dictates packaging format rather than electrical function. Confirm RoHS compliance status and material categorization requirements prior to procurement. Ensure that the requested package code matches the intended manufacturing process. Cross-reference the manufacturer part number with authorized distributors to validate authenticity and traceability.

Single Diodes Selection Notes

Select this component when a standard recovery rectifier with a 400 V reverse voltage rating is required. The DO-41 through-hole package facilitates manual assembly and standard PCB mounting. Verify thermal management needs based on the specified derating curves and maximum operating junction temperature limits. Ensure the application does not exceed the non-repetitive peak forward surge current ratings under fault conditions.

Single Diodes Part Context

This component belongs to the Vishay 1N400x series of general-purpose plastic rectifiers. The series includes variants with different reverse voltage ratings ranging from 50 V to 1000 V. All members share identical mechanical dimensions and similar electrical characteristics regarding forward current and surge capabilities, differing primarily in their maximum repetitive peak reverse voltage specifications.

Single Diodes Replacement Considerations

Direct replacements within the same Vishay family include 1N4004-E3/54, which shares identical electrical parameters but utilizes tape-and-reel packaging instead of ammo pack.

Single Diodes FAQ

What is the maximum non-repetitive peak forward surge current?

The maximum non-repetitive peak forward surge current is 30 A for an 8.3 ms single half sine-wave superimposed on rated load, and 45 A for a square waveform at 25 °C.

Does the E3 suffix change the electrical performance?

No, the E3 suffix indicates RoHS compliance and commercial grade material categorization. It meets JESD 201 class 1A whisker test requirements but does not alter the electrical characteristics of the device.
