CMJH100 TR PBFREE

Overview

The Central Semiconductor CMJH100 TR PBFREE is a surface mount silicon field effect current regulator diode housed in an SOD-123FL epoxy molded case. It provides a nominal regulator current of 10 mA with a maximum rating of 12 mA at a limiting voltage of 3.5 V. The device supports a peak operating voltage of 50 V and dissipates up to 500 mW. It operates within a junction temperature range of -65°C to +150°C, featuring a minimum dynamic impedance of 0.17 MΩ and a minimum knee impedance of 6.0 kΩ.

Feature Summary

• Maintains constant current over a wide voltage range
• Utilizes low profile SOD-123FL epoxy molded package
• Designed for high reliability applications

Applications

• Applications requiring constant current regulation
• Critical circuit current limiting
• Biasing circuits for semiconductor devices

Procurement Notes

Verify the specific ordering suffix against manufacturer documentation to confirm plating options. The PBFREE designation indicates lead-free compliance. Confirm availability through authorized distributors or direct manufacturer channels as supply levels may vary. Ensure the requested quantity matches standard factory packaging configurations.

Selection Notes

Select this component when a stable 10 mA current source is required within a 50 V operational window. Verify that the thermal resistance of 180 °C/W aligns with the system's heat dissipation capabilities. Ensure the SOD-123FL footprint fits the printed circuit board layout constraints.

Part Context

This part belongs to 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 the same SOD-123FL package and general electrical characteristics structure defined by the manufacturer.

Replacement Considerations

Consult official cross-reference data for verified substitutes. Generic equivalents may differ in dynamic impedance or temperature coefficient specifications.
