CMJ0130 TR PBFREE

Overview

The CMJ0130 TR PBFREE is a surface mount silicon current limiting diode manufactured by Central Semiconductor Corp. It belongs to the CMJ series of field effect current regulator diodes designed to maintain constant current over a wide voltage range. The device is housed in an epoxy molded, low-profile SOD-123FL package. Key electrical parameters include a peak operating voltage of 100 V, a nominal regulator current of 0.13 mA, and a maximum power dissipation of 500 mW at 60°C ambient temperature. The minimum dynamic impedance is 6.0 MΩ, with a minimum knee impedance of 2,000 kΩ. The maximum limiting voltage is 0.6 V, and the temperature coefficient ranges from +2.10 to +0.10 %/°C.

Feature Summary

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

Applications

• Silicon-based field effect transistor biasing circuits
• Constant current sources for LED drivers
• Current limiting protection in electronic circuits

Procurement Notes

Verify the specific ordering suffix against manufacturer documentation to confirm plating options. The PBFREE suffix indicates lead-free compliance. Confirm packaging details such as reel or cut tape availability directly with authorized distributors or the manufacturer. Ensure the requested quantity aligns with standard factory packaging requirements to avoid additional handling fees.

Selection Notes

Select this component when a precise, low-current regulation value near 0.13 mA is required. Consider the 100 V peak operating voltage limit and the 500 mW power dissipation capability during thermal design. Evaluate the temperature coefficient range to ensure stability meets circuit requirements across the intended operating temperature range of -65°C to +150°C.

Part Context

This part is part of the CMJ0130 through CMJH220 series of surface mount silicon current limiting diodes. The series offers various nominal current selections ranging from 0.13 mA to 22.5 mA. All devices share similar physical packaging and general operational characteristics but differ in specific current regulation values and impedance parameters.

Replacement Considerations

Direct replacements must match the SOD-123FL package, 100 V peak voltage rating, and approximately 0.13 mA nominal current. Verify that substitute components offer comparable dynamic and knee impedance values to ensure identical circuit behavior.
