The FDMS8320LDC is a single N-channel MOSFET used in a variety of digital and analog circuits. It is manufactured by Fairchild Semiconductor, a leading semiconductor manufacturer.

The FDMS8320LDC is a enhancement-mode MOSFET, meaning it has a very low current draw when not used in an application, and no gate current is necessary for it to turn on. This makes it ideal for switching and isolating applications requiring a low-power device.

This MOSFET is equipped with a UIS rating of 20V and can handle up to 7A of continuous drain current. It has a very low on-state resistance of 0.065 Ω offer exceptional performance and power savings in power supply circuits. Its maximum operating temperature range is up to 175°C.

The FDMS8320LDC is commonly used in DC-DC converters, Power over Ethernet (PoE) systems, and battery back-up circuits due to its ability to rapidly switch power. It is also used in automotive and lighting applications, thanks to its high voltage and current ratings.

This MOSFET functions by being completely turned off or completely turned on. When no gate current is applied, the transistor is completely off, meaning no current flows through the drain and source terminals, resulting in the transistor being a switch. When a gate current is applied, the transistor will be completely on and current will flow from the drain to source terminal.

The transistor also has a body diode internally, which is the reverse conducting path of the MOSFET. This diode is used when the drain voltage is higher than the source voltage. This protection feature helps to keep the transistor safe during operation, which is important as it is often used in high-power, high-voltage applications.

In addition, the FDMS8320LDC is equipped with a high dV/dt rating, making it suitable for applications that require high-speed switching, such as power switching, motor control, and more. This dV/dt rating helps to ensure safe operation even in the most hostile environments.

Overall, the FDMS8320LDC is a great choice for a wide range of applications requiring low-power, high-voltage and high-current switching and isolation. Its low on-state resistance and high current and voltage ratings make it a great solution for challenging applications, while its reverse-body diode and dV/dt rating ensure safe operation for the MOSFET.
