CMPFJ310 TR

Overview

The CMPFJ310 TR is an RF small signal field-effect transistor manufactured by Central Semiconductor Corp. It is a single-element, ultra-high frequency band, silicon N-channel junction FET designed for amplifier applications. The device utilizes a surface-mount SOT-23 (TO-236-3) package with three terminals in a dual gull-wing configuration. Constructed from plastic/epoxy material, it operates in depletion mode. The component is identified as obsolete and does not meet current RoHS standards.

Feature Summary

Designed for ultra-high frequency band operations
Utilizes silicon N-channel junction technology
Configured for amplifier applications

Applications

RF amplifier circuits
Ultra-high frequency signal processing
Small signal amplification

Procurement Notes

This component is officially listed as obsolete and discontinued by the manufacturer. Procurement should focus on verifying availability through authorized distributors or secondary markets. Buyers must confirm that the specific batch meets legacy quality requirements, as the device does not comply with current RoHS directives. Cross-referencing with equivalent active parts is recommended for new designs.

Selection Notes

Select this part only for maintenance of existing equipment requiring exact replacement. The N-channel JFET architecture and SOT-23 form factor are critical constraints. Verify that the ultra-high frequency performance matches the system requirements. Due to its obsolete status, ensure supply chain stability before committing to production volumes.

Part Context

The CMPFJ310 belongs to the Central Semiconductor JFET family, specifically engineered for RF applications. It shares the SOT-23 package style with other small-signal transistors in the lineup but is distinct due to its N-channel junction construction and ultra-high frequency designation. It serves as a specialized component for high-frequency signal amplification tasks.

Replacement Considerations

No public confirmed substitute part numbers are available in the provided documentation. Users should consult manufacturer archives for potential legacy equivalents.
