1N5312 TR TIN/LEAD

Overview

The 1N5312 TR TIN/LEAD is a current regulator diode manufactured by Central Semiconductor Corp. It provides a constant current output of 4.29 mA with a maximum operating voltage of 100 V and a power dissipation rating of 500 mW. The component utilizes a round-end surface-mount package configuration, designated as TR for tape and reel packaging. This device is designed to maintain stable current levels across varying load conditions within its specified electrical limits.

Feature Summary

• Provides constant current regulation without external components
• Supports high-voltage operation up to 100 V
• Utilizes surface-mount round-end package for compact integration

Applications

• Constant current sources for LED driving
• Biasing circuits for transistors and active devices
• Current limiting protection in electronic circuits

Procurement Notes

Verify the specific suffix 'TR TIN/LEAD' against official datasheets to confirm tape-and-reel packaging and leaded finish specifications. Ensure compatibility with automated placement equipment requirements. Cross-reference part numbers with authorized distributors to confirm availability and authenticity before procurement.

Selection Notes

Select this component when a fixed 4.29 mA current source is required within a 100 V limit. Consider the 500 mW power dissipation capability during thermal design. Verify that the surface-mount form factor aligns with the target PCB layout constraints and manufacturing processes.

Part Context

This part belongs to the 1N5312 series of current regulator diodes from Central Semiconductor. These devices are engineered for applications requiring simple, reliable current control. The series offers various current ratings and voltage capabilities to suit different circuit design needs.

Replacement Considerations

Check for pin-compatible alternatives with identical 4.29 mA regulation and 100 V breakdown voltage. Verify package dimensions and thermal characteristics match the original design constraints.
