The PN4416 is an N-channel symmetrical silicon junction field-effect transistor (JFET) manufactured by onsemi. It is housed in a SOT54 envelope and designed for high-frequency applications including VHF/UHF amplifiers, oscillators, and mixers. Key electrical characteristics include low noise performance and high gain. The device allows interchangeability of drain and source connections, simplifying circuit layout. It operates as a linear system component suitable for RF signal processing tasks requiring stable impedance and minimal signal distortion.
The PN4416 belongs to the family of N-channel JFETs produced by onsemi (formerly Fairchild Semiconductor). It is functionally equivalent to devices from other manufacturers such as Siliconix and Micross Components. The component is identified by the SOT54 package type and is distinct from bipolar transistors or MOSFETs due to its junction gate structure.
