TO-247 FGY75T120SQDN Industrial IGBT – 1200V 75A Field-Stop

FGY75T120SQDN is a high-efficiency 1200V / 75A Field-Stop IGBT engineered for demanding industrial power systems. Built with ON Semiconductor’s FS7 technology, this transistor delivers fast switching, low conduction loss, and excellent thermal stability — ideal for inverters, UPS, VFD motor drives, welding machines, solar conversion, battery chargers, and high-power switching supplies.

With a power dissipation capability of up to 790W and junction temperature handling up to 175°C, the device maintains safe operation under continuous load and repetitive switching. Its built-in anti-parallel diode ensures smooth reverse conduction and improved system efficiency in inductive motor and power-conversion environments.

Designed in a rugged TO-247 through-hole package, the FGY75T120SQDN offers simple mounting, secure heat-sinking, and reliable long-term lifecycle — perfect for engineers upgrading older generations of IGBTs to modern, energy-efficient FS7 performance.
