CCLM1000 TR

Overview

The CCLM1000 TR is a silicon current regulator diode manufactured by Central Semiconductor Corp. It features a hermetically sealed glass package in the DO-35 form factor with two terminals. The device maintains a stable regulated current of 1.0 mA and exhibits a limiting voltage of 1.7 V. It operates within a temperature range of -65 °C to 200 °C and is classified as a high-reliability component.

Feature Summary

• Maintains constant current output across varying load conditions
• Hermetically sealed glass construction for environmental protection
• Designed for high reliability applications

Applications

• Current regulation in electronic circuits
• Biasing elements for transistor stages
• Protection against current surges

Procurement Notes

Verify the specific suffix 'TR' indicates tape and reel packaging if required for assembly. Confirm lead-free status and RoHS compliance details directly with the manufacturer or authorized distributor, as standard versions may contain lead. Ensure the DO-35 package dimensions match the design footprint.

Selection Notes

Select this component when a precise 1.0 mA reference current is needed in a through-hole configuration. The wide operating temperature range supports demanding environments. Verify that the 1.7 V limiting voltage aligns with the circuit's power budget and voltage headroom requirements.

Part Context

This part belongs to the CCL series of current regulator diodes from Central Semiconductor. These devices function similarly to Zener diodes but regulate current instead of voltage. The series offers various current ratings to suit different circuit needs while maintaining the robust DO-35 glass package.

Replacement Considerations

Check for equivalents such as the CCL1000 or CCL1000 TR from Central Semiconductor which share similar specifications. Other manufacturers offering DO-35 current regulator diodes with 1.0 mA rating may serve as substitutes if pinout and electrical characteristics match.
