CMJ5750 TR PBFREE

Overview

The CMJ5750 TR PBFREE is a surface-mount silicon field effect current regulator diode manufactured by Central Semiconductor Corp. It maintains a constant current over a wide voltage range within an epoxy molded SOD-123FL case. The device supports a peak operating voltage of 100 V and a power dissipation of 500 mW at 60°C ambient temperature. Nominal regulator current is 5.75 mA, with a maximum limiting voltage of 4.5 V at 0.8 times the nominal current. Operating junction temperature ranges from -65°C to +150°C.

Feature Summary

• Maintains constant current across a wide voltage range using silicon field effect technology
• Designed for high reliability applications requiring stable current regulation
• Available in low-profile epoxy molded SOD-123FL surface mount package

Applications

• Constant current sources for LED biasing
• Current limiting protection circuits
• Voltage-to-current conversion stages

Procurement Notes

Verify the specific ordering suffix against manufacturer documentation to confirm plating composition and environmental compliance status. Ensure the selected packaging format matches the intended automated assembly process requirements. Confirm that the thermal resistance parameters align with the final system's heat dissipation capabilities before finalizing procurement specifications.

Selection Notes

Select this component when a precise nominal current of 5.75 mA is required within the standard CMJ series. Verify that the circuit operates within the 100 V peak voltage limit and 500 mW power dissipation constraints. Consider the negative temperature coefficient characteristics when designing for varying thermal environments to ensure stable operation across the specified temperature range.

Part Context

This part belongs to the CMJ0130 through CMJH220 series of surface mount silicon current limiting diodes. The series offers various nominal current selections ranging from 0.13 mA to 22.5 mA in the same SOD-123FL package footprint. The CMJ5750 specifically provides a mid-range current option suitable for general-purpose regulation tasks.

Replacement Considerations

Direct substitutes include other parts within the Central Semiconductor CMJ series offering similar nominal currents. Cross-manufacturer replacements must match the SOD-123FL package, 100 V rating, and 5.75 mA nominal current specification while verifying equivalent dynamic impedance and limiting voltage parameters.
