1N4004L-T

Single Diodes Overview

The Diodes Incorporated 1N4004L-T is a single-phase, half-wave silicon rectifier designed for general-purpose applications. It features a DO-41 plastic case with bright tin-plated axial leads. The device provides a maximum DC blocking voltage of 400V and an average rectified output current of 1.0A at +75°C ambient temperature. Key electrical characteristics include a forward voltage of 1.0V at 1.0A, a peak reverse current of 5.0µA at rated voltage, and a non-repetitive peak forward surge current rating of 30A. The component operates within a junction temperature range of -65°C to +150°C.

Single Diodes Feature Summary

• Diffused junction construction ensures high current capability and low forward voltage drop.
• Glass passivated die construction provides high reliability and low reverse leakage current.
• Surge overload rating supports peak currents up to 30A for transient protection.

Single Diodes Applications

• General-purpose rectification in power supply circuits
• Polarity protection in electronic devices
• DC blocking in resistive or inductive loads

Single Diodes Procurement Notes

Verify the specific ordering suffix against official documentation to confirm packaging configuration. The 'T' suffix indicates tape and reel shipping, while other suffixes may denote bulk packaging. Confirm RoHS compliance status and lead finish specifications directly from the manufacturer's datasheet before procurement to ensure alignment with assembly requirements.

Single Diodes Selection Notes

Select this component for standard rectification tasks requiring 400V reverse voltage and 1A continuous current. Consider derating the forward current by 20% if used with capacitive loads. Ensure the operating environment stays within the specified thermal limits and verify that the DO-41 package dimensions fit the target PCB layout constraints.

Single Diodes Part Context

This part belongs to the 1N4001 through 1N4007 series of 1.0A rectifiers manufactured by Diodes Incorporated. The series utilizes diffused junction technology housed in a DO-41 plastic case. The document notes that this specific series is not recommended for new designs, suggesting consideration of alternative series like S1A-S1M for future projects.

Single Diodes Replacement Considerations

Official documentation recommends using the S1A-S1M series as replacements for new designs. Cross-manufacturer equivalents such as 1N4004G-T (Diodes Inc) or 1N4004-TP (MCC) share identical electrical ratings but require verification of mechanical tolerances and marking conventions.

Single Diodes FAQ

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

The device can withstand a non-repetitive peak forward surge current of 30A for a single half sine-wave superimposed on rated load.

How does the average forward current change with temperature?

The average rectified output current is rated at 1.0A at an ambient temperature of +75°C. Derating curves must be consulted for operation above this temperature.
