CL15MD

Current Regulation - Diodes, Transistors Overview

The Diotec Semiconductor CL15MD is a surface-mount current limiting diode housed in a DO-213AA (Plastic MiniMELF) package. It provides a nominal steady-state regulator current of 25 mA at a test voltage of 10 V, with a minimum of 21 mA and a maximum of 29 mA. The device supports a peak operating voltage of 90 V and dissipates up to 1 W of power when mounted on a PCB with 25 mm² copper pads per terminal. It operates within a junction temperature range of -50°C to +150°C, features a typical limiting voltage of 3 V at 80% of the minimum current, and has a reverse voltage rating of 0.5 V at 1 mA leakage.

Current Regulation - Diodes, Transistors Procurement Notes

Verify the specific ordering suffix when purchasing. Suffixes such as -Q indicate AEC-Q101 compliance, while -AQ denotes parts currently undergoing automotive qualification. Confirm that the required grade matches the intended application environment before finalizing orders.

Current Regulation - Diodes, Transistors Selection Notes

Select the CL15MD for applications requiring a nominal 25 mA constant current limit. Ensure the circuit design accommodates the 90 V peak operating voltage and verify thermal management requirements, as the 1 W power dissipation rating depends on specific PCB copper pad dimensions.

Current Regulation - Diodes, Transistors Part Context

This component belongs to the CL10MD through CL30MD series of SMD current limiting diodes. All members share identical mechanical data, including the DO-213AA case and 1 W power dissipation capability, differing only in their specific nominal regulator current ratings.

Current Regulation - Diodes, Transistors Replacement Considerations

Other models within the same family, specifically the CL10MD, CL20MD, and CL30MD, serve as functional substitutes if the current regulation value can be adjusted or if the specific 25 mA rating is not strictly required.
