A 2SK879-Y(TE85L,F) is a type of junction field-effect transistor (JFET). JFETs are transistors that have three-terminal elements and provide switch or amplifier type functions through the type of semiconductor material used,Typically, a JFET will consist of the source, gate and the drain. The source and the drain, the two p-type elements, are located on either side of the n-type material, the channel.

The working principle of the 2SK879-Y(TE85L,F) lies in its ability to form a reverse biased "depletion region" voltage across the channel of the JFET. When the applied voltage to the gate exceeds that of the source, the depletion region actually increases. This increase then blocks off more of the channel and prevents current from flowing, thus acting as a switch in the circuit. It can also act as an amplifier by changing its capacitance.

The 2SK879-Y(TE85L,F) is a popular choice for low-noise preamps, due to its low number of transconductance. It is also used in audio equalizations, attenuators, line drivers, and low-level switching circuits. It is useful for general-purpose applications such as robotics or even medical equipment, as well as for fuzz circuits, overdrive circuits and other guitar effects.

JFETs offer many advantages compared to their bipolar counterparts, such as lower cost and easier circuit design. They require fewer components due to their simple construction, and are also more reliable and shock resistant than bipolar transistors. As with any other component, they still require some care when selecting, as the specs may vary slightly depending on the manufacturer.

The 2SK879-Y(TE85L,F) is a reliable, general purpose choice that provides high performance with very low noise. It is an inexpensive component that can provide reliable switching and amplification in a wide range of applications. Whether you\'re looking for a low-noise preamp or a better equalizer or just need a reliable component for switching or amplification, the 2SK879-Y(TE85L,F) is worth considering.
