1N4004G

Single Diodes Overview

The onsemi 1N4004G is a glass passivated silicon rectifier diode designed for general-purpose low-power applications. It features an axial lead DO-41 (CASE 59-10) package with a peak repetitive reverse voltage of 400 V and an average rectified forward current rating 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°C 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 5 µA at rated DC voltage and 25°C.

Single Diodes Feature Summary

• Glass passivation provides high reliability and low leakage current.
• Molded epoxy plastic case ensures corrosion resistance and solderability.
• Capable of handling high forward surge currents under rated load conditions.

Single Diodes Applications

• General-purpose low-power rectification
• AC to DC power supply conversion
• Polarity protection in electronic circuits

Single Diodes Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm packaging configuration, as standard 'G' suffix parts are typically shipped in bags while 'RL' variants use tape and reel. Confirm that the component meets required environmental standards and check for any discontinuation notices regarding legacy part numbers before finalizing procurement plans.

Single Diodes Selection Notes

Select this component when a standard recovery rectifier with a 400 V blocking capability is required for low-power applications. Ensure the thermal management strategy accounts for the specified junction-to-ambient thermal resistance values based on the chosen mounting method. Verify that the operating environment remains within the specified temperature limits to maintain performance.

Single Diodes Part Context
