1N4004

Single Diodes Overview

The onsemi 1N4004 is a glass-passivated standard recovery rectifier diode designed for general-purpose low-power applications. It features an axial lead DO-41 package with a maximum repetitive peak reverse voltage of 400 V and an average rectified forward current of 1.0 A at 75°C ambient temperature. The device supports a non-repetitive peak surge current of 30 A and operates within a junction temperature range of -65 to +150°C. Electrical characteristics include a maximum instantaneous forward voltage drop of 1.1 V at 1.0 A and a maximum reverse current of 50 μA at rated DC voltage and 25°C.

Single Diodes Feature Summary

Single Diodes Procurement Notes

Verify the specific ordering suffix (e.g., G, RL, FF) to confirm packaging format such as bags, tape and reel, or fan-fold boxes. Confirm Pb-Free status and assembly location codes if required by manufacturing specifications. Check for discontinued status notices as some variants may no longer be recommended for new designs. Ensure compliance with relevant environmental regulations applicable to your region.

Single Diodes Selection Notes

Select the 1N4004 when a 400 V reverse voltage rating is required alongside a 1 A continuous current capacity. Consider thermal resistance values based on the intended mounting method, such as vector pin mounting or board ground plane configurations. Evaluate the operating temperature range to ensure suitability for environments between -65°C and +150°C. Compare against other series members like 1N4001 or 1N4005 if voltage requirements differ.

Single Diodes Part Context

The 1N4004 belongs to the 1N4001 through 1N4007 family of axial-lead standard recovery rectifiers manufactured by onsemi. These devices share identical mechanical dimensions and current ratings but vary in their peak repetitive reverse voltage capabilities. The 1N4004 specifically provides a 400 V rating, positioning it between the 1N4003 (200 V) and 1N4005 (600 V) within the series.

Single Diodes Replacement Considerations

Direct substitutes include other manufacturers' 1N4004 equivalents meeting JEDEC DO-41 standards. Verify that replacement parts maintain the same 400 V reverse voltage, 1 A forward current, and 30 A surge current ratings. Ensure compatibility with existing PCB footprints and soldering processes.
