CL20M35

Current Regulation - Diodes, Transistors Overview

The CL20M35 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 features a nominal regulator current of 20 mA with a maximum peak operating voltage of 90 V. The device dissipates up to 1 W of power when mounted on a PCB with 25 mm² copper pads per terminal. It utilizes a DO-214AC (SMA) package and supports an operating junction temperature range from -50°C to +150°C. Key electrical characteristics include a limiting voltage of 3 V at 80% of nominal current and a reverse voltage rating of 0.5 V.

Current Regulation - Diodes, Transistors Procurement Notes

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

Current Regulation - Diodes, Transistors Selection Notes

Select the CL20M35 when a precise 20 mA nominal current is required. Ensure the circuit design accommodates the 90 V maximum working voltage. For designs requiring compensation for temperature drift, utilize a parallel resistor as documented in the application notes. Verify thermal resistance requirements against the specified 70 K/W junction-to-ambient value.

Current Regulation - Diodes, Transistors Part Context

This component belongs to the CL15M35 through CL40M35 series of SMD current limiting diodes. All members share identical mechanical dimensions and maximum ratings, differing only in their nominal regulator current values ranging from 15 mA to 40 mA. The series is optimized for commercial and industrial grade applications requiring reliable constant current sources.

Current Regulation - Diodes, Transistors Replacement Considerations

Direct substitutes within the same family include the CL15M35 for lower current needs or the CL40M35 for higher current requirements. Cross-manufacturer replacements must match the 20 mA nominal current, 90 V peak voltage, and DO-214AC package constraints.
