The JFET transistor, or junction field effect transistor, is a type of field-effect transistor that utilizes an electric field to control the shape and thus the conductivity of a channel of one type of charge carrier in a semiconductor material.The P1086 is a depletion-mode, N-channel JFET specifically designed for low-noise, high-gain aircraft applications.

The P1086 is constructed with a JFET channel in a standard plastic TO-90 package. The JFET channel consists of a n-type gate region surrounded by p-type substrate. The junction between the substrate and the gate region forms the gate-to-source (Gs) junction which, when forward-biased, develops a depletion region between the n-type source and the p-type substrate. The depletion region will cause a decrease in the number of charge carriers in the channel around the source, controlling the conduction of current through the device.

The drain-source voltage applied to the device affects the amount of current that will pass through the device as the voltage will control the size of the depletion region. A higher drain-source voltage will increase the size of the depletion region and thus reduce the amount of current passing through the device. When the drain-source voltage is decreased the depletion region will become smaller and the current through the device will increase.

The gate-source voltage applied to the device also affects the conductivity of the device as it will control the bias of the gate-source junction, as well as the size of the depletion region. A negative gate-source voltage will increase the bias of the junction and decrease the size of the depletion region, which, in turn, will increase the current passing through the device. Similarly, a positive gate-source voltage will reduce the bias of the junction and increase the size of the depletion region, which will decrease the current passing through the device.

The P1086 JFET is designed for use in aircraft applications and is capable of operating at temperatures up to 150°C. It provides excellent high-gain characteristics and low-noise performance which make it an ideal choice for aircraft applications. It also features a low leakage current, a high input impedance and a low on-resistance, making it an excellent choice for applications such as low-noise, high-gain amplifiers, audio and switching circuits.

The P1086 JFET offers excellent characteristics and superior performance in aircraft applications. Its low-noise, high-gain capabilities, as well as its low leakage current and low on-resistance make it an ideal choice for applications such as low-noise amplifiers and audio circuitry. Its high temperature capability makes it an ideal choice for applications operating under extreme temperatures. For these reasons, the P1086 JFET has become a popular choice in aircraft applications.
