MRF6S23140HR5 is a RF power dual N-channel MOSFET manufactured by Microsemi Corporation, specifically designed for use in consumer radio frequency (RF) power amplifiers. It combines a high drain-source voltage (VDS) of 140 volts and high power output level of 22 watts. As such, it is widely used in consumer communication systems and particularly in wireless base station amplifiers.

Generally, MRF6S23140HR5 is made up of two N-channel MOSFETs placed next to each other. Each MOSFET is composed of four parts: the drain, the gate, the source and the body. The drain and source terminals of each MOSFET are connected in parallel to form one common source and drain, while each gate terminal is connected to its own control terminal. Each MOSFET can be independently switched "ON" or "OFF" via its own control terminal. The combined MOSFET is also known as a packaged comparison pair.

The primary application of MRF6S23140HR5 is in RF power amplifiers and other RF applications that require medium power levels. This is due to its relatively high levels of power output and stability. It is also frequently used in high-bandwidth and low noise applications, such as communication systems and satellite receivers. As such, it is seen in both consumer and commercial systems.

The working principle of MRF6S23140HR5 is based on the concept of field-effect transistors (FETs). A FET is a three-terminal unipolar semiconductor device, employing the electrostatic motion of electrons in a metal-oxide-semiconductor (MOS) structure, which acts as a switch. This then serves to regulate current flow between two terminals. The three terminals are the drain, the gate and the source, with the gate placed between the drain and source. The current flow is regulated by a gate voltage applied to the gate. When the gate voltage is increased, the channels in the MOSFET become wider, allowing more electrons to move from the source to the drain, resulting in a larger current flow.

In the case of MRF6S23140HR5, a gate voltage is applied to the two parallel gate terminals of the MOSFET, resulting in a larger current flow between the drains and sources. The applied voltage affects the electron density of the two MOSFETs separately, allowing them to be switched on and off independently. This provides for greater power output and stability.

MRF6S23140HR5 is a versatile RF power dual N-channel MOSFET and is widely used in various RF applications, such as base station amplifiers, communication systems, and satellite receivers. It offers superior power output levels, presence and stability, and is simple to operate, making it a popular choice for many applications.
