CL15M45

Current Regulation - Diodes, Transistors Overview

The Diotec Semiconductor CL15M45 is a surface-mount current limiting diode designed for low-power applications. It operates within an SMB (DO-214AA) package and supports a maximum peak operating voltage of 90 V with a total power dissipation of 1 W at 50°C ambient temperature. The nominal regulator current is specified at 15 mA, with a minimum of 12 mA and a maximum of 17 mA when tested at a voltage of 10 V. The device features a reverse voltage of 0.5 V and a junction capacitance of 5 pF. It functions reliably across a storage and operating junction temperature range of -50°C to +150°C.

Current Regulation - Diodes, Transistors Procurement Notes

Verify the specific suffix designation when ordering, as variants such as -AQ indicate AEC-Q101 qualification while standard versions lack this automotive certification. Confirm that the required current rating aligns with the 15 mA nominal specification for the target circuit design. Ensure compatibility with the SMB surface-mount footprint during PCB layout planning.

Current Regulation - Diodes, Transistors Selection Notes

Select the CL15M45 when a precise constant current source near 15 mA is required for low-voltage loads. Consider parallel configurations if the application demands currents exceeding the single-device maximum limits. Evaluate thermal resistance parameters, specifically the 50 K/W junction-to-ambient value, to ensure adequate heat dissipation on the printed circuit board copper pads.

Current Regulation - Diodes, Transistors Part Context

This component belongs to the CL15M45 through CL40M45 series of SMD current limiting diodes manufactured by Diotec Semiconductor. The series shares common mechanical data, including the DO-214AA package and 1 W power dissipation capability, while varying primarily in their nominal regulator current ratings from 15 mA to 40 mA.
