CMJH080 TR PBFREE

Overview

The Central Semiconductor CMJH080 TR PBFREE is a surface mount silicon field effect current regulator diode designed to maintain constant current over a wide voltage range. It is housed in an epoxy molded, low profile SOD-123FL case. The device features a peak operating voltage of 50 V and a power dissipation rating of 500 mW at 60°C ambient temperature. The nominal regulator current is 8.2 mA, with a maximum limiting voltage of 3.1 V. Operating and storage junction temperatures range from -65°C to +150°C.

Feature Summary

• Provides constant current regulation across a wide voltage range
• Manufactured in a low profile epoxy molded SOD-123FL package
• High reliability construction suitable for critical applications

Applications

• Applications requiring constant current over a wide voltage range
• Critical circuit designs needing special current selections

Procurement Notes

Verify the specific ordering suffix requirements when purchasing. The PBFREE suffix indicates lead-free plating compliance. Confirm availability through authorized distributors or direct manufacturer channels. Ensure the requested quantity matches standard packaging configurations. Review the latest datasheet version for any updates to electrical characteristics or mechanical dimensions before finalizing procurement orders.

Selection Notes

Select the CMJH080 based on the required nominal regulator current of 8.2 mA. Ensure the circuit operates within the 50 V peak operating voltage limit. Verify that the thermal environment allows for 500 mW power dissipation at the expected ambient temperature. Consider the temperature coefficient range of -0.25 to -0.45 %/°C for precision applications. Compare against other series members if different current levels are needed.

Part Context

This component belongs to the CMJ0130 through CMJH220 series of surface mount silicon current limiting diodes. The series offers various special selections of regulator current for critical applications. All devices share the same SOD-123FL package and general electrical structure, differing primarily in their specific current regulation values and marking codes.

Replacement Considerations

Direct substitutes must match the SOD-123FL package, 50 V peak voltage, and approximately 8.2 mA regulator current. Verify that alternative components meet the same power dissipation and temperature range specifications. Check for equivalent dynamic and knee impedance characteristics to ensure similar performance in the target circuit.
