Current Regulation - Diodes, Transistors Procurement Notes

Verify the specific ordering suffix required for plating configuration when purchasing. The standard designation includes PBFREE for lead-free compliance. Confirm the tape and reel packaging format matches the intended automated assembly process. Ensure the part number aligns with the manufacturer's current documentation to avoid discrepancies in electrical characteristics or marking codes.

Current Regulation - Diodes, Transistors Selection Notes

Select this component based on the required nominal regulator current of 1.1mA and the 100V peak operating voltage limit. Consider the thermal resistance of 180°C/W and the 500mW power dissipation capability for heat management. Verify that the SOD-123FL package dimensions fit the available board space and that the operating temperature range meets the environmental requirements.

Current Regulation - Diodes, Transistors Part Context

This device belongs to the CMJ0130 through CMJH220 series of surface mount silicon current limiting diodes. The series provides various special selections of regulator current (IP) to accommodate different design needs.
