CL40M35

Current Regulation - Diodes, Transistors Overview

The CL40M35 is a surface-mount current limiting diode manufactured by Diotec Semiconductor, designed for constant current regulation in low-power applications. It operates within the CL15M35 to CL40M35 series and utilizes an SMA (DO-214AC) package. The device features a nominal regulator current of 40 mA, with a minimum of 34 mA and a maximum of 46 mA at an anode-cathode voltage of 10 V. It supports a peak operating voltage of 90 V and handles a total power dissipation of 1 W when mounted on a PCB with 25 mm² copper pads per terminal. The junction temperature range spans from -50°C to +150°C.

Current Regulation - Diodes, Transistors Procurement Notes

Verify the exact ordering suffix when purchasing. Standard commercial grade parts lack automotive certification. Suffix -Q indicates AEC-Q101 compliance, while -AQ denotes parts currently undergoing qualification. Confirm these designations match project reliability requirements before procurement.

Current Regulation - Diodes, Transistors Selection Notes

Select this component for applications requiring stable current regulation up to 40 mA. Ensure the circuit design accommodates the specified 90 V peak operating voltage. For designs needing higher current capacity, utilize parallel configurations as documented in the application notes. Verify thermal management aligns with the 70 K/W thermal resistance to ambient rating.

Current Regulation - Diodes, Transistors Part Context

This part belongs to the CL15M35 through CL40M35 series of SMD current limiting diodes. All variants share identical mechanical dimensions, packaging standards, and maximum voltage ratings. The primary distinction across the series is the nominal regulator current value, which scales from 15 mA to 40 mA based on the specific model number.
