CMJD2000 TR

Overview

The CMJD2000 TR PBFREE is a surface mount current regulator diode manufactured by Central Semiconductor Corp. It belongs to the CPL03-CMJD series and provides a nominal regulating current of 2.0 mA. The device supports a maximum peak operating voltage of 100 V and features a maximum limiting voltage of 2.7 V. It operates within a temperature range of -55°C to +150°C. Key impedance parameters include a minimum dynamic impedance of 300 kOhms and a minimum knee impedance of 30 kOhms. The component is supplied in a reel packaging format.

Feature Summary

• Provides stable constant current regulation for circuit protection and biasing applications
• Operates reliably across an extended industrial temperature range up to 150°C
• Designed for surface mount assembly using standard SOT-23 compatible footprints

Applications

• LED driver circuits requiring constant current regulation
• Transistor biasing networks for stable operating points
• Protection circuits against overcurrent conditions

Procurement Notes

Verify the specific suffix 'TR PBFREE' to confirm the reel packaging and lead-free compliance status. Ensure the ordering quantity aligns with the manufacturer's standard reel pack size requirements. Cross-reference the datasheet for exact mechanical dimensions to validate PCB footprint compatibility before finalizing procurement orders.

Selection Notes

Select this component when a fixed 2.0 mA current source is required within a 100 V voltage window. Compare the 300 kOhms dynamic impedance against load variations to ensure sufficient regulation stability. Verify that the thermal management strategy accommodates the specified 150°C maximum junction temperature limit during operation.
