1N4004RLG

Single Diodes Overview

The onsemi 1N4004RLG is a glass-passivated standard recovery rectifier diode designed for general-purpose low-power applications. It features an axial lead DO-41 (CASE 59-10) package and operates with a peak repetitive reverse voltage of 400 V and an average rectified forward current of 1.0 A. The device supports a non-repetitive peak surge current of 30 A and maintains a maximum instantaneous forward voltage drop of 1.1 V at 1.0 A. It functions within a junction temperature range of -65°C to +150°C.

Single Diodes Feature Summary

• Glass passivation protects the junction against mechanical stress and ensures stable electrical performance.
• Molded epoxy plastic case provides corrosion resistance and meets UL flammability classification 94V-0.
• Axial leads are readily solderable, supporting standard through-hole mounting techniques.

Single Diodes Applications

• General-purpose low-power rectification in electronic circuits
• AC to DC conversion in power supply designs
• Protection against reverse polarity in DC circuits

Single Diodes Procurement Notes

Verify that the ordering suffix RL indicates tape and reel packaging containing 5000 units per reel. Confirm the presence of the Pb-Free indicator or microdot marking to ensure compliance with environmental standards. Cross-reference the specific part number against official discontinuation lists to confirm availability for new designs.

Single Diodes Selection Notes

Select this component when a 400 V blocking capability is required alongside a 1 A continuous current rating. Ensure the application environment remains within the specified -65°C to +150°C operating temperature range. Verify that the axial lead form factor fits the target PCB layout constraints.

Single Diodes Part Context

This part belongs to the 1N400x series of axial lead standard recovery rectifiers manufactured by onsemi. The series includes variants rated from 50 V to 1000 V, sharing identical physical dimensions and thermal characteristics while differing in voltage ratings. The 1N4004 variant specifically targets 400 V applications within this family.

Single Diodes Replacement Considerations

Compatible substitutes include other manufacturers' 1N4004 diodes in the DO-41 package. Verify that replacement parts match the 400 V reverse voltage, 1 A forward current, and 30 A surge current specifications to maintain circuit integrity.
