2SC393400L

Overview

The Panasonic 2SC3934 is a silicon NPN epitaxial planar transistor designed for high-frequency wide-band low-noise amplification. It operates in the SMini type package, which facilitates equipment downsizing and supports automatic insertion via tape or magazine packing. The device features a transition frequency of up to 4.5 GHz at VCE = 10 V and IC = 10 mA. Key electrical ratings include a collector-base voltage of 15 V, a collector-emitter voltage of 12 V, and a maximum collector current of 30 mA continuous (50 mA peak). Power dissipation is rated at 150 mW with a junction temperature limit of 150 °C.

Feature Summary

• Engineered for high-frequency wide-band low-noise amplification applications
• Features a high transition frequency suitable for RF signal processing
• Utilizes an SMini type package to enable equipment miniaturization
• Supports automated manufacturing processes through tape and magazine packing compatibility

Applications

• High-frequency wide-band low-noise amplification circuits
• General electronic equipment such as office machines and measuring instruments
• Communications equipment requiring RF signal processing

Procurement Notes

Verify the current lifecycle status directly with Panasonic Industry before design finalization. The component datasheet indicates maintenance or discontinuation stages may apply. Confirm availability through authorized distributors and ensure compliance with RoHS directives. Request the latest product standards to validate specifications against current manufacturing data prior to procurement.

Selection Notes

Select this component for designs requiring low noise figures around 1.3 dB at 0.8 GHz. Ensure operating conditions remain within the absolute maximum ratings, specifically the 12 V collector-emitter voltage and 150 mW power dissipation limits. Consider the thermal environment carefully, as performance characteristics vary with ambient temperature changes from -25°C to +75°C.

Part Context

The 2SC3934 belongs to the category of silicon NPN epitaxial planar transistors manufactured by Panasonic Electronic Components. It is distinct from general-purpose switching transistors due to its optimized RF parameters. The device is intended for standard applications in communications and measuring instruments rather than specialized safety or aerospace systems.

Replacement Considerations

Consult official documentation for verified substitute part numbers. Cross-referencing requires matching the SMini package dimensions, 4.5 GHz transition frequency, and low-noise amplifier specifications to ensure functional equivalence in existing circuit designs.
