CCLM0500 BK

Overview

The CCLM0500 BK is a silicon current regulator diode manufactured by Central Semiconductor Corp. It is housed in a hermetically sealed DO-35 glass package with two pins. The device provides a stable regulated current of 500µA at a typical limiting voltage of 1.7V. It operates within a temperature range of -65°C to +200°C and features low dynamic impedance for precise current control.

Feature Summary

• Provides constant current regulation independent of supply voltage variations
• Hermetically sealed DO-35 glass package ensures environmental stability
• Capable of operation at elevated temperatures up to 200°C

Applications

• Constant current sources for LED biasing
• Voltage reference stabilization circuits
• Transistor biasing networks

Procurement Notes

Verify the specific suffix 'BK' against the manufacturer's official datasheet to confirm lead-free compliance and hermetic sealing status. Ensure the ordered part matches the required 500µA current rating and DO-35 package dimensions for your circuit design.

Selection Notes

Select this component when a compact, high-temperature current source is required. The DO-35 package suits through-hole applications. Verify that the 1.7V drop voltage fits within your available headroom and that the 500µA output meets the load requirements.

Part Context

This part belongs to the CCL series of current limiting diodes from Central Semiconductor. These devices are designed to replace resistors in applications requiring stable current flow. The series offers various current ratings in standard axial packages.

Replacement Considerations

Check for equivalents such as the CCL1000 or CCL2000 if different current levels are acceptable. Verify pinout compatibility and thermal characteristics before substituting.
