CCLM1500 TR

Overview

The CCLM1500 TR is a surface mount silicon current regulator diode manufactured by Central Semiconductor Corp. It provides a constant current of 1.72mA with a maximum limiting voltage of 4V. The device is housed in an SOD-80 package and operates within a temperature range of -65°C to 150°C.

Feature Summary

• Provides stable constant current regulation for circuit protection
• Utilizes silicon technology for reliable performance
• Designed for surface mount assembly applications

Applications

• Current limiting in electronic circuits
• Biasing networks requiring constant current
• Protection against overcurrent conditions

Procurement Notes

Verify the specific suffix 'TR' indicates tape and reel packaging when ordering. Confirm RoHS compliance status as required by project specifications. Ensure the SOD-80 footprint matches the design layout. Check datasheet for exact electrical tolerances before finalizing procurement.

Selection Notes

Select this component for applications requiring precise current regulation in a compact surface mount form factor. Consider the 1.72mA output current and 4V breakdown voltage limits. Evaluate thermal management requirements given the 150°C junction temperature rating. Compare against through-hole alternatives if space constraints allow.

Part Context

This part belongs to Central Semiconductor's line of silicon current regulator diodes. It serves as a surface mount alternative to axial leaded versions like the CCL1500. The series offers high reliability for discrete semiconductor applications.

Replacement Considerations

Direct substitutes include other 1.72mA current regulator diodes in SOD-80 packages. Verify pinout compatibility and electrical parameter overlaps. Cross-reference with CCL1500 for functional equivalence if package changes are acceptable.
