NE5550779A-A, is a common p–n–p plastic encapsulated RF Transistor device. The purpose of this device is to switch or amplify oscillating signals, especially radio frequency signals. This transistor can be found in a variety of consumer and industrial applications, ranging from radio and television frequency applications to switching circuits.

NE5550779A-A belongs to the family of field effect transistors (FETs). FETs are basically three-terminal devices that can control current flow between two terminals by varying a control voltage applied to a third terminal. These devices operate by creating an electric field within a semiconductor material, which allows the current to flow from one region to another. FETs are classified as junction FETs and metal–oxide–semiconductor FETs (MOSFETs).

NE5550779A-A is a MOSFETs. MOSFETs are made from a substrate material and several other layers of materials that are deposited on it. The substrate material is usually silicon, and the other layers of materials include gate oxide, electrically conductive material and a dielectric material. When the gate oxide is exposed to an electric field, this produces a change within the gate oxide which then allows current to flow through the substrate. This is known as Drain-Source Current, and is the main principle of FET operation.

NE5550779A-A is a N–Channel, depletion MOSFET with a built-in gate protection diode and a variety of protection features. It has a low drain-source on-resistance, low gate threshold voltage and low capacitance. These features make it ideal for RF applications. It is also suitable for Signal Mixing, Negation Amplifier, Analog Switches, Switching PLL/VCO and Class-D/Loudspeaker Audio Amplifiers.
