2SC3931GCL

Overview

The Panasonic 2SC3931GCL is a silicon NPN epitaxial planar transistor designed for high-frequency amplification. It operates with a collector-emitter voltage of 20 V and a maximum collector current of 15 mA. The device features a transition frequency (fT) ranging from 450 MHz to 650 MHz at 200 MHz, ensuring effective RF performance. Electrical characteristics include a forward current transfer ratio (hFE) between 65 and 260, a power gain of 24 dB at 100 MHz, and a noise figure of 3.3 dB. It utilizes an S-Mini package for downsizing.

Feature Summary

• Optimized for RF amplification in FM/AM radio applications
• High transition frequency supporting efficient signal processing
• S-Mini type package enabling equipment downsizing and automatic insertion

Applications

• RF amplification for FM radios
• RF amplification for AM radios
• General-purpose high-frequency amplification circuits

Procurement Notes

Verify the specific ordering suffix 'GCL' against official Panasonic documentation to confirm tape packing specifications. Confirm the product lifecycle status on the manufacturer's website, as maintenance or discontinuation notices may apply. Ensure compliance with RoHS directives and verify that the component meets the intended application requirements before finalizing procurement.

Selection Notes

Select this component when designing circuits requiring high-frequency amplification with low noise figures. Consider the 20 V collector-emitter voltage limit and 15 mA maximum current rating during circuit design. Evaluate the S-Mini package dimensions for PCB layout constraints. Verify hFE rank requirements (C or D) based on the specific gain needs of the amplifier stage.

Part Context

The 2SC3931G belongs to Panasonic's lineup of silicon NPN epitaxial planar transistors. It is specifically engineered for high-frequency applications, distinguishing it from general-purpose switching transistors. The S-Mini package variant facilitates automated assembly processes while maintaining a compact footprint suitable for modern consumer electronics.

Replacement Considerations

Consult official Panasonic cross-reference lists for verified substitutes. Ensure any replacement matches the S-Mini package, 20 V VCEO rating, and comparable fT and hFE specifications. Verify pinout compatibility to prevent circuit damage during installation.
