CMJ1500 TR PBFREE

Overview

The CMJ1500 TR PBFREE is a surface mount silicon field effect current regulator diode manufactured by Central Semiconductor Corp. It operates within the CMJ0130 through CMJH220 series and is housed in an epoxy molded, low-profile SOD-123FL case. The device provides a nominal regulator current of 1.5 mA with a minimum dynamic impedance of 0.45 MΩ and a minimum knee impedance of 70 kΩ at specified test conditions. It supports a peak operating voltage of 100 V and dissipates up to 500 mW of power. The component functions reliably across a junction temperature range from -65°C to +150°C.

Feature Summary

• Provides constant current regulation over a wide voltage range
• Manufactured in a low-profile epoxy molded SOD-123FL package
• Designed for high reliability applications requiring stable current limiting

Applications

• Applications requiring constant current over a wide voltage range
• Critical applications needing special selections of regulator current
• Silicon field effect current limiting circuits

Procurement Notes

Verify the specific ordering suffix against manufacturer documentation to confirm plating options. The standard designation includes PBFREE for lead-free compliance. Confirm the reel packaging quantity matches the required production volume. Ensure the SOD-123FL footprint aligns with the target PCB design before finalizing procurement orders.

Selection Notes

Select this component when a precise nominal current of 1.5 mA is required within a 100 V peak operating limit. Consider the 500 mW power dissipation capability and the -65°C to +150°C operating temperature range. Evaluate the dynamic and knee impedance specifications against circuit stability requirements. Verify that the SOD-123FL package dimensions fit the available board space constraints.

Part Context

This part belongs to the Central Semiconductor 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. All devices share the same SOD-123FL package and general electrical characteristics structure, differing primarily in their specific regulator current ratings and associated impedance values.

Replacement Considerations

Direct substitutes must match the SOD-123FL package, 1.5 mA nominal current, and 100 V peak voltage rating. Verify that alternative components maintain similar dynamic and knee impedance profiles to ensure circuit performance parity.
