84,045 productsAbout MOSFETs
MOSFETs (Metal-Oxide-Semiconductor Field-Effect Transistors) are voltage-controlled semiconductor switches designed to manage high-efficiency power conversion, motor control, and load switching in modern electronic systems. By utilizing a gate voltage to control the current flowing between drain and source terminals, MOSFETs offer extremely fast switching speeds and ultra-low on-resistance (RDSon), making them far superior to bipolar transistors in high-frequency switch-mode power supplies (SMPS).
This massive subcategory indexes N-channel and P-channel MOSFETs, spanning low-voltage signal switches, logic-level drive FETs, high-current automotive power switches, and high-voltage Silicon Carbide (SiC) MOSFETs. Selection criteria focus on drain-source breakdown voltage (VDSS), continuous drain current (ID), on-resistance (RDSon, measured in milli-ohms), gate charge (Qg, which affects switching speed), and package thermal characteristics (SOT-23, DFN, TO-220, D2PAK).
