1N5303 TR PBFREE

Overview

The 1N5303 TR PBFREE is a silicon field-effect current regulator diode manufactured by Central Semiconductor Corp. It provides a regulated current of 1.60 mA with a power operating voltage (PoV) of 100 V and a maximum power dissipation of 600 mW. The device is housed in an axial DO-204AH package and is supplied in a reel packaging format. It complies with RoHS standards, ensuring environmental safety for electronic assemblies.

Feature Summary

• Maintains constant current output across varying load conditions
• Operates within a high power operating voltage range
• Utilizes silicon field-effect technology for stable regulation

Applications

• LED driver circuits
• Current limiting applications
• Biasing networks for semiconductor devices

Procurement Notes

Verify the specific suffix 'TR PBFREE' to confirm reel packaging and lead-free composition. Ensure the required axial DO-204AH form factor matches the target PCB layout. Confirm that the 1.60 mA regulation current aligns with the circuit design requirements before finalizing procurement orders.

Selection Notes

Select this component when a simple, passive current regulation solution is required without active feedback loops. Consider the 100 V power operating voltage limit to ensure adequate headroom for the application. Verify thermal management capabilities given the 600 mW power dissipation rating in enclosed environments.

Part Context

This part belongs to the 1N5283 series of silicon current limiting diodes from Central Semiconductor. These components are designed as two-terminal devices that regulate current flow similarly to how Zener diodes regulate voltage, providing a reliable alternative for constant current sources in discrete electronics.

Replacement Considerations

Cross-reference with other 1.60 mA current regulator diodes in the DO-204AH package. Verify pinout compatibility and electrical parameter tolerances such as current tolerance and breakdown voltage before substituting.
