onsemi FGH4L40Tx 1200V/40A Field Stop Power IGBTs

onsemi FGH4L40Tx 1200V/40A Field Stop Power Insulated-Gate Bipolar Transistors (IGBTs) are engineered for high-efficiency switching in demanding power applications. These IGBTs feature low conduction and switching losses, ideal for use in motor drives, Uninterruptible Power Supply (UPS) systems, and renewable energy inverters. With robust short-circuit capability and soft switching performance, the IGBTs support high-frequency operation while maintaining thermal stability. The optimized design of the onsemi Field Stop technology-based FGH4L40Tx IGBTs enable reliable performance in both hard- and soft-switching topologies, helping designers meet stringent efficiency and power density requirements in industrial and energy-focused systems.
