1N4004G

Single Diodes Overview

The 1N4004G is a glass passivated silicon rectifier diode manufactured by Taiwan Semiconductor. It features a DO-204AL (DO-41) axial leaded package designed for general-purpose rectification applications. The device provides a maximum repetitive peak reverse voltage of 400V and an average forward rectified current rating of 1.0A at 25°C ambient temperature. Key electrical characteristics include a low forward voltage drop, high surge current capability rated up to 30A, and low reverse leakage current. The component operates within a junction temperature range from -55°C to +150°C.

Single Diodes Feature Summary

• Glass passivated chip junction construction ensures stable performance and reliability under various operating conditions.
• High forward surge current capability allows the device to withstand transient overload events without failure.
• Low power loss and high efficiency are achieved through optimized forward voltage drop characteristics.

Single Diodes Applications

• General purpose rectification in AC to DC power supply circuits
• Reverse polarity protection in electronic systems
• DC output rectification in battery chargers

Single Diodes Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to confirm packaging type, such as Ammo Pack or Tape & Reel, as these affect handling and quantity. Ensure compliance with RoHS Directive 2011/65/EU and WEEE 2002/96/EC requirements if applicable to your assembly process. Confirm halogen-free status according to IEC 61249-2-21 definitions when sourcing from authorized distributors.

Single Diodes Selection Notes

Select this component for applications requiring standard recovery characteristics with a 400V blocking voltage. The DO-41 package is suitable for through-hole mounting on PCBs where space permits axial leads. Consider the thermal derating curves for currents exceeding 1.0A or ambient temperatures above 25°C to maintain safe operating limits.

Single Diodes Part Context

This part belongs to the 1N400x series of general-purpose silicon rectifiers, widely used in consumer electronics and industrial equipment. The 'G' suffix typically denotes glass passivation and compliance with environmental directives like RoHS. It serves as a direct replacement for legacy 1N4004 devices while offering improved consistency and regulatory compliance.

Single Diodes Replacement Considerations

Direct substitutes include 1N4004 from other manufacturers such as onsemi, Fairchild, and UTC, provided they meet the same 400V/1A specifications and DO-41 package dimensions. Verify pinout compatibility and thermal resistance values before substitution.
