2SC370400L

Overview

The Panasonic 2SC3704 is a silicon NPN epitaxial planar transistor designed for UHF band low-noise amplification. It operates with a collector-emitter voltage of 10 V and a collector current of 80 mA, housed in a Mini3-G1 (EIAJ SC-59) package. Key electrical parameters include a transition frequency (fT) of 6 GHz at 20 mA, a forward transfer gain (|S21e|^2) of 13 dB, and a maximum unilateral power gain of 14 dB at 0.8 GHz. The device achieves a noise figure between 1.0 and 1.7 dB at 7 mA. Absolute maximum ratings specify a collector-base voltage of 15 V, emitter-base voltage of 2 V, and collector power dissipation of 200 mW.

Procurement Notes

Verify the current lifecycle status before procurement, as the datasheet indicates potential maintenance or discontinued stages. Confirm that the specific order quantity aligns with tape or magazine packing requirements to ensure compatibility with automatic insertion processes during manufacturing assembly.

Selection Notes

Select this component when designing circuits requiring low noise figures around 1.0 to 1.7 dB at UHF frequencies. Ensure the operating collector current remains within the specified range to maintain the guaranteed transition frequency and forward transfer gain characteristics while respecting the 200 mW power dissipation limit.

Part Context

This component belongs to the category of silicon NPN epitaxial planar transistors manufactured by Panasonic Electronic Components. It is specifically engineered for high-frequency performance in the UHF band, distinguishing it from general-purpose switching transistors through its optimized noise and gain specifications.

Replacement Considerations

Consult official manufacturer documentation for confirmed substitute part numbers. Verify pinout compatibility and electrical parameter equivalence if considering alternative components for existing designs.
