CL30MD

Current Regulation - Diodes, Transistors Overview

The Diotec Semiconductor CL30MD is a surface-mount current limiting diode housed in a MiniMELF (DO-213AA) plastic package. It provides a nominal steady-state regulator current of 40 mA with a minimum of 36 mA and maximum of 44 mA at a test voltage of 10 V. 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 leakage current of 0.5 V at 1 mA.

Current Regulation - Diodes, Transistors Procurement Notes

Verify the specific ordering suffix against official documentation before procurement. Suffixes such as -Q indicate AEC-Q101 compliance, while -AQ denotes qualification status. Confirm that the required automotive or commercial grade aligns with the project specifications. Ensure the component version matches the datasheet revision date to guarantee accurate electrical parameters and mechanical dimensions.

Current Regulation - Diodes, Transistors Selection Notes

Select the CL30MD when a nominal current of 40 mA is required within a MiniMELF footprint. Consider parallel configurations if currents exceeding 44 mA are necessary. Verify thermal resistance requirements, noting the typical junction-to-ambient value is 75 K/W. Ensure the application voltage does not exceed the 90 V peak rating. Check for temperature drift compensation needs using external resistors as described in the application notes.

Current Regulation - Diodes, Transistors Part Context

The CL30MD belongs to the CL10MD through CL30MD series of SMD current limiting diodes manufactured by Diotec Semiconductor. These components share the same MiniMELF package and 90 V voltage rating but differ in their regulated current levels. The series is designed for commercial and industrial applications requiring reliable current regulation in compact form factors.
