Overview
The Diotec Semiconductor CL40M45 is a surface-mount current limiting diode housed in an SMB (DO-214AA) package. It provides a nominal regulator current of 40 mA with a maximum operating voltage of 90 V and a power dissipation rating of 1 W at 50°C ambient temperature. The device operates within a junction temperature range of -50°C to +150°C, featuring a reverse voltage of 0.5 V and a junction capacitance of 5 pF. Thermal resistance values are specified as 50 K/W from junction to ambient and 10 K/W from junction to terminal.
Feature Summary
- Supports parallel operation to achieve higher total current intensity
- Compliant with RoHS directives, REACH regulations, and conflict mineral standards
Applications
- Low power LED drivers
- Battery chargers
- Constant current regulators for simple sensor circuits
- Power supply for microcontrollers
Procurement Notes
Verify the specific ordering suffix when purchasing. Standard versions are designated as commercial or industrial grade. Suffixes such as -Q indicate AEC-Q101 compliance, while -AQ denotes AEC-Q101 qualification. Confirm these designations align with project reliability requirements before procurement.
Selection Notes
Select this component for applications requiring precise constant current regulation without complex circuitry. Ensure the thermal environment allows for 1 W dissipation on a PCB with 25 mm² copper pads per terminal. Verify that the peak operating voltage does not exceed 90 V under all transient conditions.
Part Context
This part belongs to the CL15M45 through CL40M45 series of SMD current limiting diodes manufactured by Diotec Semiconductor. The series shares identical mechanical dimensions and electrical characteristics regarding voltage and power ratings, differing primarily in their nominal current limits ranging from 15 mA to 40 mA.
Replacement Considerations
No direct public substitute part numbers are documented for this specific component. Designers must evaluate alternative current limiting diodes based on matching SMB packaging, 90 V breakdown voltage, and 40 mA nominal current specifications.
