CL05M6F

Overview

The CL05M6F is an SMD current limiting diode from Diotec Semiconductor, housed in a compact SOD-123FL package. It provides a nominal regulating current (IPnom) of 5.6 mA with a minimum of 4.5 mA and maximum of 6.7 mA. The device supports a peak operating voltage (VAK) of 190 V and dissipates up to 0.7 W at 25°C ambient temperature on standard PCB pads. It operates within a junction temperature range of -50°C to +150°C. Key electrical characteristics include a limiting voltage of 2.0 V at IL = 80% IPnom and a typical steady-state regulator current of 5.4 V at VT = 10 V.

Feature Summary

• Provides stable current regulation for simple sensor circuits and low power LED drivers
• Supports parallel operation to achieve higher current ratings or different IP values
• Compliant with RoHS (exempt 7a-I), REACH, and Conflict Minerals regulations

Applications

• Constant current regulators for simple sensor circuits
• Low power LED drivers
• Battery chargers

Procurement Notes

Verify the specific ordering suffix when purchasing. The base model CL05M6F represents the standard commercial/industrial grade version. Suffixes such as -Q indicate AEC-Q101 compliance, while -AQ denotes qualification status. Confirm that the required automotive grade matches the project specifications before finalizing orders, as these suffixes denote distinct reliability certifications rather than functional changes.

Selection Notes

Select the CL05M6F when a precise 5.6 mA nominal current is required for biasing sensors or driving low-power LEDs. Ensure the circuit design accommodates the 190 V peak voltage rating and 0.7 W power dissipation limits under expected thermal conditions. Consider parallel configurations if higher currents are needed, utilizing external resistors for temperature drift compensation as outlined in the application notes.

Part Context

This component belongs to the CLxxM6F series of SMD current limiting diodes manufactured by Diotec Semiconductor. The series includes variants with nominal currents ranging from 5.6 mA to 30 mA, all sharing similar mechanical dimensions and voltage ratings. The CL05M6F specifically targets applications requiring lower current stabilization compared to its higher-current siblings like the CL10M6F or CL30M6F.

Replacement Considerations

No public substitute part numbers are documented in the official datasheet.
