1N5307 TR PBFREE

Overview

The 1N5307 TR PBFREE is a silicon field-effect current regulator diode manufactured by Central Semiconductor. It provides a nominal regulated current of 2.4 mA with a maximum limiting voltage of 2 V. The device supports a maximum repetitive peak reverse voltage of 100 V and handles a maximum power dissipation of 600 mW. Packaged in axial configurations such as DO-35 or DO-204AH, the component is supplied in reel packaging for automated assembly processes.

Feature Summary

• Provides stable constant current regulation via silicon field-effect technology
• Supports high-voltage operation up to 100 V reverse blocking capability
• Designed for through-hole mounting in standard axial packages

Applications

• Constant current sources for LED biasing
• Current limiting protection in electronic circuits
• Biasing elements for transistor amplifier stages

Procurement Notes

Verify that the specific order matches the 'TR' suffix designation, which indicates reel packaging rather than bulk or tape-and-reel variations. Confirm RoHS compliance status directly with the manufacturer documentation, as regulatory details may vary by production batch. Ensure the required axial package type (DO-35 or DO-204AH) aligns with the PCB footprint design before finalizing procurement.

Selection Notes

Select this component when a fixed 2.4 mA regulation point is required within a 100 V system limit. Consider the 600 mW power dissipation rating to ensure adequate thermal management in the target application environment. Evaluate the axial leaded package constraints against available board space and automated placement equipment compatibility.

Part Context

This part belongs to the 1N5307 series of silicon current regulator diodes produced by Central Semiconductor. The series includes variants with different current ratings and packaging options. The 'PBFREE' designation indicates lead-free construction, while 'TR' specifies the reel supply method used for high-volume manufacturing integration.

Replacement Considerations

Cross-reference with other manufacturers offering equivalent 2.4 mA current regulator diodes in axial packages. Verify that substitute parts maintain identical electrical parameters, specifically the 2.4 mA nominal current and 100 V reverse voltage rating, to ensure circuit functionality remains unchanged.
