CCLM0035 BK

Overview

The CCLM0035 BK is a silicon field effect current regulator diode manufactured by Central Semiconductor Corp. It provides constant current regulation over a wide voltage range, with a specified regulator current of 0.035mA and a maximum limiting voltage of 0.4V. The device operates within a temperature range of -65°C to 200°C and features a dynamic impedance of 8,000,000 ohms. It is housed in a hermetically sealed DO-35 glass package.

Feature Summary

• Silicon field effect construction for stable current regulation
• Hermetically sealed DO-35 glass package for high reliability
• Constant current output across a wide voltage range

Applications

• Current limiting circuits
• Constant current sources
• High reliability electronic systems

Procurement Notes

Verify the specific suffix 'BK' against the manufacturer's official datasheet to confirm it denotes the standard through-hole DO-35 variant rather than a specialized military or tape-and-reel configuration. Ensure compliance requirements are met as the component may be classified as non-RoHS depending on the specific manufacturing batch and terminal material specifications.

Selection Notes

Select this component when a precise 35µA current limit is required in a ruggedized environment. The wide operating temperature range up to 200°C makes it suitable for high-thermal applications where standard plastic packages would fail. Verify that the 0.4V limiting voltage drop fits within the system's headroom constraints.

Part Context

This part belongs to the CCL series of current limiting diodes from Central Semiconductor. It shares functional similarities with the CCL0035 but utilizes a specific packaging or qualification variant indicated by the suffix. It serves as a discrete alternative to complex active current source circuits in simple protection roles.

Replacement Considerations

Direct substitutes include the Digitron Semiconductors CCL0035 and the Central Semiconductor CCL0035. When replacing, ensure the replacement device maintains the same 0.035mA regulator current and DO-35 package form factor to preserve circuit board layout compatibility.
