BFR93AR,215 Working Principle

The BFR93AR,215 is an NPN Amplifier/Switch Transistor which is mainly used for high-frequency applications. It consists of two transistors: a BJT and a FET, in a double-layered monolithic integrated circuit. The BJT works as a low-power amplifier and the FET works as a high-speed switch.

The BJT works in the common-collector configuration, where a voltage drop is generated across the collector-emitter junction of the BJT. The voltage drop is then applied to the gate of the FET, thereby controlling the FET\'s current. This current is amplified and passed to the output load.

The FET works in the enhancement mode, where the voltage across the drain-source junction is increased when a voltage is applied to the gate of the FET. This increases the current flowing through the drain-source junction and thus amplifies the signal. The BJT and the FET work together to provide a high input impedance and a low output impedance, which makes them ideal for high-frequency applications.
