CL20M35R7

Current Regulation - Diodes, Transistors Overview

The CL20M35R7 is a surface-mount current limiting diode manufactured by Diotec Semiconductor, belonging to the CL15M35 through CL40M35 series. It provides a nominal regulation current of 20 mA with a minimum of 17 mA and a maximum of 23 mA at an anode-cathode voltage of 10 V. The device supports a peak operating voltage of up to 90 V and dissipates a total power of 1 W 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 and features a reverse voltage rating of 0.5 V. The component utilizes a DO-214AC (SMA) package and exhibits a typical thermal resistance from junction to ambient of 70 K/W.

Current Regulation - Diodes, Transistors Procurement Notes

Verify that the ordering suffix R7 corresponds to the specific tape and reel packaging configuration required for automated assembly processes. Confirm compliance with commercial grade reliability standards rather than automotive grades unless explicitly specified as AEC-Q101 compliant or qualified variants. Ensure the procurement documentation matches the exact part number designation to avoid discrepancies in component specifications.

Current Regulation - Diodes, Transistors Selection Notes

Select this component for applications requiring precise constant current regulation without complex circuitry. Evaluate the thermal resistance characteristics against the expected ambient temperature conditions to ensure the junction temperature remains within the specified operational limits. Consider parallel configurations if the application demands current handling capabilities exceeding the single unit's nominal rating.

Current Regulation - Diodes, Transistors Part Context

This component belongs to the CL15M35...CL40M35 family of SMD current limiting diodes produced by Diotec Semiconductor. The series offers various nominal currents ranging from 15 mA to 40 mA within the same SMA package outline.
