2SK208-R(TE85L,F) Discrete Semiconductor Products

The 2SK208-R (TE85L,F) is a field-effect transistor (FET) that is part of the JFET family. FETs are a type of transistor that uses electric fields to control the current flowing through a channel between terminals on opposite sides of the device. This type of transistor is especially useful in circuits where fine control over the output current is required. The 2SK208-R is a depletion mode JFET, meaning that the gate current flows in the same direction as the source current, and this current increases as the gate voltage is reduced. As such, the source and drain circuits are normally open in the absence of an electric field.

The 2SK208-R is a bipolar junction transistor (BJT) with a single gate structure. It is typically used for low-level audio or radio frequency (RF) signal amplification due to its low gate capacitance and good frequency response. It features a maximum voltage rating of 20 volts, a gate-to-source capacitance of 0.06 pF, and a gate-to-drain capacitance of 0.05 pF, making it well-suited for use in small signal amplifiers operating up to 500 MHz.

The 2SK208-R can be used in a variety of applications including signal processing, audio, video, and other low-level electronic systems. In signal processing, the 2SK208-R is often used as an active element to control signal gain, levels, and distortion. It is often used in audio applications, such as mixing and mastering, to fine-tune signal levels to provide enhanced sound quality. In video applications, the device is commonly used to control video signal level and reduce noise.

In addition to signal processing, the 2SK208-R can also be used in power management and testing applications. Power management applications use the device to control and manage power levels, while testing applications use it for current modulation and power measurements. The 2SK208-R is also often used in RF systems, such as in radio transmitters, receivers, and antennas, where it is used to control signal gain and reduce distortion.

The 2SK208-R is a dependable and reliable device, with a low leakage current, a high gain-bandwidth product, and good input and output impedance characteristics. Its low gate capacitance and higher voltage rating make it an attractive solution for many applications. Overall, the 2SK208-R is a great option for designers looking for a high-performance, cost-effective FET that can be used in a variety of applications.
