BSN20BKR is a type of single junction field effect transistor (FET), which is also referred to as a Junction Gate Field Effect Transistor (JGFET). It is a device that is constructed with a layer of semiconductor material sandwiched between two metal contacts, one of which acts as the anode and the other as the cathode. The device is then connected to a source of electricity and the gate controls the flow of current through the system, either allowing or blocking it from passing. This is critical in controlling the amount of current that flows into or out of a circuit.

The BSN20BKR FET is capable of handling large currents and has a very low threshold voltage, making it very useful in applications such as switching supplies, audio amplifiers, interface circuits, and power amplifiers. This type of transistor has the ability to withstand larger amounts of power without damage, and its low threshold voltage allows it to be used in circuits where the source voltage is highly varied. The device also features a relatively low ON-resistance, meaning that it will draw less power when it is in operation.

The working principle behind the BSN20BKR FET is based on the process of field electron injection. This involves a metal electrode being placed at the gate of the FET and charged with an electric field, which then injects electrons into the channel of the transistor. This electron injection results in a charge buildup in the channel and thus a current that can be controlled. By altering the voltage at the gate, the current through the channel can be regulated, allowing the transistor to either switch on or off.

Since the gate electrode of the FET is insulated from the rest of the device, much higher voltages and multiple signals can be simultaneously applied to the gate. This makes the BSN20BKR FET highly useful for applications requiring multiple high-voltage signals or a high degree of control. Additionally, the device is also capable of very high frequency operation, up to 500MHz.

In applications such as data transmitters, the BSN20BKR FET can be used to provide an ON-OFF control on a single signal, while in other applications such as radio frequency (RF) amplifiers, multiple FETs can be connected in series to provide gain control. The device also finds use in power MOSFET gate drivers, which are used to drive large MOSFETs and IGBTs in switching power supplies, power amplifiers, and other circuits using high current.

The BSN20BKR FET is suitable for use in a variety of industrial, military and commercial applications due to its low threshold voltage and high current capabilities. Additionally, because of its high frequency operation and multiple gate control capabilities, it is an ideal choice when a circuit requires multiple, high frequency signals to be processed or controlled simultaneously.
