1N4003 TR

Overview

The Central Semiconductor Corp 1N4003 TR is a silicon rectifier diode belonging to the 1A series. It features a maximum average forward rectified current of 1 A and a peak repetitive reverse voltage rating of 200 V. The device utilizes a glass passivated junction for enhanced reliability and is housed in a DO-41 axial leaded package. The suffix 'TR' indicates that the component is supplied in tape and reel packaging, suitable for automated surface mount or through-hole assembly processes.

Feature Summary

• Glass passivated junction construction
• High surge current capability
• Axial leaded DO-41 package

Applications

• General purpose rectification
• Power supply circuits
• Reverse polarity protection

Procurement Notes

Verify the specific manufacturer source before ordering, as this part number has been discontinued by Central Semiconductor Corp. Confirm availability with authorized distributors or alternative manufacturers. Ensure the replacement component matches the required electrical specifications and physical dimensions for your design.

Selection Notes

Select this component for applications requiring standard recovery characteristics and a 200 V reverse voltage rating. Consider the DO-41 package size for board space constraints. Verify thermal management requirements based on the expected forward current load and ambient operating temperature conditions.

Part Context

This component is part of the widely used 1N400x series of general-purpose silicon rectifiers. These devices are standardized across multiple manufacturers to provide interchangeable performance for basic power conversion tasks. The 1N4003 variant specifically targets circuits needing a 200 V blocking voltage threshold.

Replacement Considerations

Central Semiconductor designated the 1N4007 TR as the official replacement for the 1N4003 TR. When sourcing alternatives from other manufacturers, ensure the substitute part meets the same 1 A current and 200 V voltage ratings.
