CMJ1000 TR PBFREE

Overview

The CMJ1000 TR PBFREE is a surface mount silicon field effect current regulator diode manufactured by Central Semiconductor Corp. It maintains a constant current over a wide voltage range, utilizing the epoxy molded SOD-123FL case. The nominal regulator current (IP) is 1.1 mA, with a maximum rating of 1.32 mA and a minimum of 0.88 mA at VT=25V. It supports a peak operating voltage of 100 V and dissipates up to 500 mW. The device operates within a junction temperature range of -65°C to +150°C.

Feature Summary

• Designed for applications requiring constant current regulation across a wide voltage range
• Manufactured in a low-profile epoxy molded SOD-123FL case
• Utilizes silicon field effect technology for high reliability

Applications

• Current limiting circuits
• Constant current sources
• Biasing networks for semiconductor devices

Procurement Notes

Verify the specific ordering suffix against manufacturer documentation to confirm plating options. The 'PBFREE' designation indicates lead-free compliance, while alternative suffixes may denote different material compositions. Confirm package availability and standard lead times directly with authorized distributors or the manufacturer before finalizing procurement plans.

Selection Notes

Select this component when a precise nominal current of 1.1 mA is required within the CMJ series. Ensure the circuit design accommodates the specified dynamic impedance and limiting voltage parameters. Verify that the SOD-123FL footprint matches the PCB layout requirements and that the thermal resistance characteristics are suitable for the intended power dissipation environment.

Part Context

This part belongs to the CMJ0130 through CMJH220 series of surface mount silicon current limiting diodes from Central Semiconductor Corp. The series offers various special selections of regulator current (IP) tailored for critical applications. All devices in this family share similar packaging and operational principles but differ in their specific current ratings and electrical characteristics.

Replacement Considerations

Direct substitutes within the same series include other CMJ variants such as CMJ1500 or CMJ0750 if current adjustment is permissible. Cross-manufacturer replacements must match the SOD-123FL package, 100V peak voltage rating, and 500mW power dissipation limits. Verify pinout compatibility and electrical tolerances before implementation.
