CMJH150 TR PBFREE

Overview

The Central Semiconductor CMJH150 TR PBFREE is a surface mount silicon field effect current regulator diode housed in an SOD-123FL epoxy molded case. It provides a nominal regulator current of 15 mA with a maximum range of 12 to 18 mA at VT=25V. The device supports a peak operating voltage of 50 V and dissipates up to 500 mW. Key electrical parameters include a minimum dynamic impedance of 0.03 MΩ, a minimum knee impedance of 2.0 kΩ, and a maximum limiting voltage of 4.3 V. Operating temperatures range from -65°C to +150°C.

Feature Summary

• Maintains constant current over a wide voltage range
• Low profile SOD-123FL package design
• High reliability construction

Applications

• Applications requiring constant current regulation
• Critical applications needing special current selections
• Current limiting circuits

Procurement Notes

Verify the specific ordering suffix against manufacturer documentation to confirm plating options. The PBFREE designation indicates lead-free compliance. Confirm packaging details such as reel or cut tape availability directly with authorized distributors or the manufacturer to ensure alignment with production requirements.

Selection Notes

Select this component when a stable 15 mA current source is required within a 50 V limit. Ensure the application operates within the specified -65°C to +150°C junction temperature range. Verify that the thermal resistance of 180 °C/W is compatible with the PCB layout and ambient conditions for proper heat dissipation.

Part Context

This part belongs to the CMJ0130 through CMJH220 series of surface mount silicon current limiting diodes. The series offers various nominal currents from 0.13 mA to 25 mA. The CMJH150 specifically targets the 15 mA regulation point, distinguishing it from lower current variants like the CMJH100 or higher current models like the CMJH180.

Replacement Considerations

Direct substitutes within the same family include the CMJH120 (12 mA) or CMJH180 (18 mA) if current tolerance allows adjustment. Cross-manufacturer equivalents must match the SOD-123FL footprint, 50 V rating, and 15 mA nominal current specification.
