The 20NF20 is 200V, 18A, Power MOSFET. This Power MOSFET series realized with STMicroelectronics unique STripFET™ process has specifically been designed to minimize input capacitance and gate charge. It is therefore suitable as primary switch in advanced high efficiency isolated DC-DC converters.

A 200V, 18A power MOSFET refers to a specific type of power Metal-Oxide-Semiconductor Field-Effect Transistor (MOSFET) designed to handle high voltage and current levels in power electronic applications. The specifications “200V” and “18A” indicate the maximum voltage and current ratings of the MOSFET, respectively.

Here’s what these specifications mean:

Voltage Rating (200V): This indicates that the MOSFET can handle a maximum voltage of 200 volts. MOSFETs with higher voltage ratings are suitable for applications that require switching or controlling higher voltage levels, such as in power supplies or motor control circuits.

Current Rating (18A): This specifies the maximum current that the MOSFET can handle continuously without exceeding its thermal limits. In this case, the MOSFET can handle a continuous current of up to 18 amperes. Power MOSFETs with higher current ratings are typically used in applications that require handling larger currents, such as motor drives or power converters.

Power MOSFETs are popular in power electronics due to their low on-resistance (RDS(on)), high switching speeds, and efficient operation. They are commonly used in a wide range of applications, including motor control, power supplies, inverters, and DC-DC converters.
