STMicroelectronics MOSFET Distributor | STPOWER N-Channel

BeiLuo supplies genuine STMicroelectronics STPOWER MOSFETs, the N-channel silicon devices that switch power in motor drives, power supplies, inverters and DC-DC converters. The portfolio is built on ST's STripFET and MDmesh technologies, which trade off on-resistance, gate charge and ruggedness to suit different switching frequencies and topologies. STripFET devices use a trench gate structure for low on-resistance at moderate voltages, which suits low-voltage, high-current applications such as battery-powered motor drives and DC-DC stages. MDmesh devices use a super-junction structure for low on-resistance at high voltage, which suits offline power supplies and other high-voltage switching. Choosing a MOSFET is a balance among breakdown voltage, current rating, on-resistance, gate charge and thermal package, and the right part depends on the switching frequency and the loss budget of the design. Low on-resistance reduces conduction loss, while low gate charge reduces switching loss, and the two usually trade against each other. ST also offers SiC MOSFETs for the highest-voltage, highest-efficiency designs. Every device BeiLuo ships is factory-traceable and includes an import declaration, a certificate of origin and a RoHS compliance file. Our FAE team helps you match the MOSFET to your topology, gate drive and thermal design, balancing on-resistance, gate charge and package against the switching frequency and the thermal path of the design.
