1N4004GH

Single Diodes Overview

The 1N4004GH is a silicon rectifier diode manufactured by Taiwan Semiconductor Corporation. It features a standard recovery characteristic with a maximum average forward current of 1 A and a peak repetitive reverse voltage rating of 400 V. The device utilizes a glass passivated junction to ensure high reliability and low leakage current. It is housed in a DO-41 (DO-204AL) axial leaded package designed for through-hole mounting. Key electrical parameters include a maximum non-repetitive peak forward surge current of 30 A, a maximum DC blocking voltage of 400 V, and a maximum RMS voltage of 280 V. The component supports an operating junction temperature range from -65°C to +175°C.

Single Diodes Feature Summary

• Glass passivated chip junction construction provides high reliability and low power loss.
• High efficiency design characterized by low forward voltage drop.
• Capable of handling high forward surge currents for robust circuit protection.
• Compliant with RoHS Directive 2011/65/EU and WEEE 2002/96/EC standards.

Single Diodes Applications

• General purpose rectification in AC to DC power supply circuits.
• Reverse polarity protection in electronic equipment.
• DC output rectification in battery chargers.
• Freewheeling diodes in inductive load switching applications.

Single Diodes Procurement Notes

Verify the specific suffix 'GH' against official Taiwan Semiconductor documentation to confirm exact packaging configuration and material compliance status. Ensure that the procurement source provides valid traceability data matching the manufacturer's part identification. Confirm that the delivered components meet the specified JEDEC mechanical outline requirements for the DO-41 package.

Single Diodes Selection Notes

Select this component when a standard recovery rectifier with a 400 V reverse voltage rating and 1 A continuous current capacity is required. The DO-41 package is suitable for through-hole PCB layouts where axial leads are preferred. Consider the 175°C maximum junction temperature for applications involving elevated ambient temperatures or significant self-heating during operation.

Single Diodes Part Context

This component belongs to the 1N400x series of general-purpose silicon rectifiers. The series offers various voltage ratings ranging from 50 V to 1000 V while maintaining a consistent 1 A current capability. The 1N4004 variant specifically targets applications requiring a 400 V blocking voltage. The 'G' designation typically indicates glass passivation, while 'H' often denotes specific tape-and-reel packaging variations.

Single Diodes Replacement Considerations

Compatible substitutes include the 1N4004G and 1N4004RLG from onsemi, which share identical electrical ratings and DO-41 packaging. Other manufacturers such as Vishay and Diotec offer equivalent parts like the 1N4004GP. Verify that any replacement maintains the same glass passivation technology and thermal characteristics.
