2SC39350PL

Overview

The Panasonic 2SC3935 is a silicon NPN epitaxial planar transistor designed for high-frequency amplification, oscillation, and mixing applications. It operates within a collector-emitter voltage of 10 V and a collector current limit of 50 mA, with a maximum power dissipation of 150 mW at 25°C ambient temperature. The device features a transition frequency (fT) ranging from 1.4 to 2.5 GHz, enabling effective performance in RF circuits. Packaged in the S-Mini type SC-70 format, it supports automated insertion via tape packing. Electrical characteristics include a forward current transfer ratio (hFE) between 75 and 220, depending on the specific rank classification.

Procurement Notes

Verify component authenticity through authorized distribution channels. Confirm that the received parts match the specified SC-70 package dimensions and marking symbols. Ensure storage conditions comply with manufacturer guidelines regarding shelf life and moisture sensitivity levels before assembly.

Selection Notes

Select this component when designing circuits requiring high-frequency operation up to 2.5 GHz. Consider the low collector output capacitance for signal integrity. Verify that the required hFE gain falls within the available P or Q ranks. Ensure the operating environment remains within the specified junction temperature limits.

Part Context

This component belongs to the Panasonic discrete semiconductor transistor family. It utilizes an epitaxial planar structure optimized for small-signal RF applications. The S-Mini package provides a compact footprint compared to traditional leaded packages, supporting modern surface-mount manufacturing processes.

Replacement Considerations

Consult official documentation for verified substitute part numbers. Cross-referencing requires matching electrical parameters such as transition frequency, voltage ratings, and package type to ensure functional compatibility in existing designs.
