1N4004GP

Single Diodes Overview

The Diotec Semiconductor 1N4004GP is a standard recovery rectifier diode designed for general-purpose applications. It features a maximum repetitive peak reverse voltage of 400 V and an average forward rectified current rating of 1 A. The device utilizes a glass passivated chip junction within a DO-41 molded plastic package, ensuring UL flammability classification 94V-0 compliance. Key electrical characteristics include a maximum forward voltage drop of 1.1 V at 1 A and a low reverse leakage current of 5 µA at 400 V. It supports a non-repetitive peak forward surge current of 30 A and operates across a junction temperature range from -55 °C to +175 °C.

Single Diodes Procurement Notes

Verify the specific manufacturer designation when sourcing, as the 1N4004GP part number is widely used by multiple semiconductor producers including Micro Commercial Components and others. Confirm that the component meets RoHS directives and halogen-free requirements if specified for your assembly process. Ensure the package type matches the DO-41 footprint required for your PCB layout. Check datasheets for exact thermal resistance values relevant to your enclosure design.

Single Diodes Selection Notes

Select this component for circuits requiring robust standard recovery performance with high surge tolerance. The 400 V reverse voltage rating provides sufficient margin for 220 V AC mains rectification. The DO-41 through-hole package facilitates easy manual soldering and prototyping. Consider the 1.1 V forward voltage drop for efficiency calculations in low-voltage output stages. Verify operating temperature limits against your environmental conditions.

Single Diodes Part Context

The 1N4004 belongs to the widely recognized 1N400x series of silicon rectifier diodes. This series is standardized for general-purpose power conversion tasks. The '4' suffix typically denotes the 400 V reverse voltage rating, distinguishing it from other variants like the 1N4001 (50 V) or 1N4007 (1000 V). These devices are fundamental components in power supply designs worldwide.

Single Diodes Replacement Considerations

Direct pin-compatible substitutes include 1N4004-E3/53 from Vishay and 1N4004G-T from Diodes Incorporated. Ensure replacement parts maintain the same DO-41 package and electrical ratings. Verify that any alternative meets the same safety certifications and material specifications required by your design.
