1N4004RLG Description

Short technical summary and product information.

The 1N4004RLG is a standard recovery rectifier diode from On Semiconductor designed for general-purpose low-power applications. It is rated for a peak repetitive reverse voltage of 400V with a non-repetitive peak reverse voltage of 480V, providing robust voltage handling. The device delivers an average rectified current of 1A with a forward voltage of 1.1V at 1A, making it suitable for power supply and AC-to-DC conversion circuits where moderate voltage and current levels are required.

 

This rectifier features a standard recovery time greater than 500ns, which is typical for 50/60Hz line frequency rectification. The junction is diffused in an axial-lead glass-passivated plastic package (DO-204AL / DO-41) that ensures corrosion resistance and solderable terminals. The cathode is indicated by a polarity band for easy identification.

 

The part is through-hole mounted with axial leads, suitable for manual or wave soldering processes. Operating temperature range is -65°C to +150°C as specified in the datasheet. The package supports tape-and-reel packaging for automated assembly. This device is a member of the widely used 1N400x series of rectifiers, offering a cost-effective solution for low-power rectification needs.
