2SC39310CL

Overview

The Panasonic 2SC39310CL is a silicon NPN epitaxial planar transistor designed for high-frequency amplification in FM/AM radios. It utilizes an S-Mini (SMini3-G1) surface-mount package to facilitate equipment downsizing and automated insertion. The device operates with a collector-emitter voltage of 20 V, a collector current of 15 mA, and a power dissipation of 150 mW at 25°C. Key electrical characteristics include a transition frequency ranging from 450 MHz to 650 MHz and a noise figure as low as 3.3 dB at 100 MHz.

Feature Summary

• Optimized for RF amplification within FM and AM radio circuits
• High transition frequency supporting operation up to 650 MHz
• Compact S-Mini type package enabling automatic insertion

Applications

• RF amplification stages in FM receivers
• RF amplification stages in AM receivers
• General-purpose high-frequency signal processing

Procurement Notes

Verify the component lifecycle status on the manufacturer's official website before procurement, as this series may be classified under maintenance or discontinued plans. Confirm that the specific ordering suffix matches the required hFE rank classification. Ensure compliance with RoHS directives applicable to your region prior to finalizing orders.

Selection Notes

Select this component when designing compact RF front-ends requiring high transition frequencies and low noise figures. Verify that the operating ambient temperature remains within the specified range to maintain the 150 mW power dissipation rating. Ensure the circuit design accommodates the maximum collector-base voltage of 30 V and emitter-base voltage of 3 V to prevent breakdown.

Part Context

This component belongs to the Panasonic 2SC3931 series of silicon NPN transistors. It is specifically engineered for high-frequency applications where small form factors are critical. The SMini3-G1 package allows for efficient use of printed circuit board space compared to larger through-hole alternatives.

Replacement Considerations

Consult the manufacturer's official documentation for verified substitute part numbers. Cross-referencing requires matching the SMini3-G1 package, NPN polarity, and equivalent RF performance metrics such as transition frequency and noise figure.
