STMicroelectronics IGBT Distributor | STPOWER Field-Stop

BeiLuo supplies genuine STMicroelectronics STPOWER IGBTs, the insulated-gate bipolar transistors that switch high currents at high voltages in motor drives, inverters, induction heating and welding equipment. ST builds its IGBTs on a trench gate field-stop structure, which combines low saturation voltage with fast switching and robust short-circuit behaviour, and it offers several series tuned for different applications. The HB series is optimized for high-speed switching with a soft-recovery antiparallel diode, which suits motor drives and inverters that switch at moderate to high frequency. The V series is tuned for a balance of conduction and switching loss in general-purpose applications, and other series address low-frequency, high-current work such as welding. Choosing an IGBT is a balance among blocking voltage, current rating, saturation voltage, switching speed and the antiparallel diode, and the right part depends on the topology and the switching frequency. The antiparallel diode matters as much as the transistor in a bridge, because its recovery behaviour sets the switching loss and the EMI. 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 IGBT and its diode to your topology, gate drive and thermal design.
