The PSMN038-100K 518 is a Fairchild Enhancement Mode Power MOSFET (Metal-Oxide Semiconductor Field-Effect Transistor) device. It is among the pioneer members of its family to have an operating temperature range from -55C to +150C, with a breakdown voltage of 100V.A MOSFET is a type of Field Effect Transistor (FET) that uses an electric charge to modify the conductivity of a semiconductor material, such as silicon or germanium. FETs are switched by controlling the voltage applied to the gate of the transistor. The PSMN038-100K 518 is a single-gate MOSFET, meaning it has only one voltage-controlled gate that is used to activate or deactivate the device.The working principle of this specific MOSFET is rather simple. When the gate voltage is below the threshold voltage (Vgs-th), it will not conduct any current. If the gate voltage exceeds the threshold voltage, the drain-source current will increase and will be able to control a load connected to the drain. The drain-source current is known as the drain current Id.MOSFETs are commonly used in various control and switching applications, such as motor control, switching circuits and audio amplifiers. In addition, they can also be used for applications such as power supplies, inverters and converters, RF power amplifiers and antenna switches.The PSMN038-100K 518MOSFET is especially suitable for DC and AC motor control, and it is able to carry 100A currents in Continuous Conduction Mode (CCM) as well as in Discontinuous Conduction Mode (DCM). It is also suitable for applications such as DC-DC converters, AC-DC converters and fast switching applications, due to its good switching performance at high temperatures and its low on-state resistance (Rds-on).

The main feature of the PSMN038-100K 518 is its small footprint, which allows designers to reduce the overall size of their design, while still providing a high-performance solution. It also offers excellent thermal dissipation capabilities and stable performance over the entire operating temperature range.The PSMN038-100K 518 is a typically used in automotive systems, industrial control and in-board systems, due to its good operating temperature range, low on-state resistance, high current demands and robustness.In conclusion, the PSMN038-100K 518 is a power MOSFET device with excellent switching performance, suitable for dc and ac motor control, as well as fast switching applications. It has a gate-source breakdown voltage of 100V, an excellent thermal dissipation capability, and a rather small size, making it a great choice for applications that require high current demands.
