The MRF8S21200HSR5 is an N-Channel Enhancement-Mode Field-Effect Transistor (FET) for RFApplications. It is designed for Class A linear amplified applications and features low gate-to-source capacitance and low junction-to-drain capacitance. This makes it suitable for use at frequencies up to 30MHz, at a supply voltage of up to 30V.

The MRF8S21200HSR5 is constructed using planar technology. It consists of a source and drain region, with additional drain contact provided on the underside of the device. The source connection is accessible through the source-terminal. The drain contact is connected to the source region through a series of metal gate fingers. This gate arrangement allows the gate voltage to be precisely adjusted, controlling the drain current.

The working principle of the MRF8S21200HSR5 is very simple. When a voltage is applied to the gate, it creates an electric field in the channel region between the source and drain. This field repels electrons from the gate and attracts them to the drain. This creates an inversion layer in the channel, allowing current to flow from the source to the drain.

The MRF8S21200HSR5 is ideally suited for applications such as power amplifiers, audio amplifiers, switching circuits, and other RF applications. It is very reliable and has a high threshold voltage, which helps to ensure safe and efficient operation of these devices. The low input capacitance also makes it ideal for high frequency applications, such as RF communication.

The MRF8S21200HSR5 can be used in a variety of circuit configurations. It can be used in common source, common drain, and cascode arrangements. Additionally, it can be used in complementary metal–oxide–semiconductor (CMOS) circuits, which provide excellent compatibility with digital circuitry. This makes the MRF8S21200HSR5 very versatile and suitable for applications ranging from analog to digital operation.

The MRF8S21200HSR5 has a number of advantages over conventional FETs. The gate voltage can be precisely adjusted, allowing it to be used in linear and digital circuits. Additionally, the low input capacitance makes it ideal for high frequency applications, providing excellent performance at frequencies up to 30MHz.
