CCLM0300 BK

Overview

The CCLM0300 BK is a silicon current regulator diode manufactured by Central Semiconductor Corp. It features a hermetically sealed glass DO-35 package and provides a stable regulated current of 0.3 mA. The device operates with a low voltage drop of approximately 1.7 V and supports a peak operating voltage up to 100 V. It is designed for applications requiring precise current limiting or regulation in compact electronic circuits.

Feature Summary

• Provides constant current regulation within the specified operating range
• Hermetically sealed glass construction ensures environmental stability
• Compact axial leaded form factor suitable for space-constrained designs

Applications

• Current limiting in transistor biasing circuits
• Constant current sources for LED drivers
• Voltage reference stabilization in analog circuits

Procurement Notes

Verify the specific suffix 'BK' against the manufacturer's official datasheet to confirm it denotes the standard black band marking or a specific variant, as suffixes can indicate packaging or compliance differences. Ensure the DO-35 package compatibility matches your PCB footprint requirements before ordering.

Selection Notes

Select this component when a fixed low-current regulation of 0.3 mA is required. Compare its 100 V maximum voltage rating against circuit peaks. Consider the DO-35 package size relative to available board space. Verify thermal dissipation needs, as power handling is limited by the small glass envelope.

Part Context

This part belongs to the CCL series of current limiting diodes from Central Semiconductor. These devices are silicon-based junction regulators designed to maintain a nearly constant current over a wide range of voltages. The series offers various current values to suit different circuit requirements.

Replacement Considerations

Direct substitutes include other manufacturers' DO-35 current regulator diodes with identical 0.3 mA regulation and similar voltage ratings. Verify pinout orientation and electrical characteristics match exactly before substitution.
