CMJ2000 TR PBFREE

Overview

The Central Semiconductor CMJ2000 TR PBFREE is a surface mount silicon field effect current regulator diode housed in an SOD-123FL case. It provides a nominal regulator current of 2.0 mA with a maximum rating of 2.32 mA and a minimum of 1.68 mA at VT=25V. The device supports a peak operating voltage of 50 V and dissipates up to 500 mW. Electrical characteristics include a minimum dynamic impedance of 0.35 MΩ, a minimum knee impedance of 50 kΩ, and a maximum limiting voltage of 2.3 V. The temperature coefficient ranges from -0.15 to -0.42 %/°C.

Feature Summary

• Maintains constant current over a wide voltage range
• Manufactured in a low-profile epoxy molded SOD-123FL case
• Designed for high reliability applications

Applications

• Applications requiring constant current regulation
• Critical circuit protection scenarios

Procurement Notes

Verify the specific ordering suffix against manufacturer documentation to confirm plating options. The PBFREE designation indicates lead-free compliance. Confirm package type and reel specifications directly with authorized distributors or the manufacturer to ensure alignment with production requirements.

Selection Notes

Select this component when a precise nominal current of 2.0 mA is required within the CMJH series. Ensure the application voltage remains below the 50 V peak operating limit. Consider the thermal resistance and power dissipation constraints for proper heat management in the design.

Part Context

This part belongs to the CMJ0130 through CMJH220 series of surface mount silicon current limiting diodes. The series offers various special selections of regulator current (IP) to accommodate critical application needs across different current levels.

Replacement Considerations

Direct substitutes within the same family include CMJ1500 and CMJ2700, though their nominal currents differ. Verify functional equivalence based on specific current tolerance and impedance requirements before substitution.
