The STMicroelectronics STGW80V60F is a 600 V, 120 A Trench Field Stop IGBT in a TO-247-3 through-hole package. It is designed for medium-frequency switching applications such as motor drives, inverters, welding machines, and uninterruptible power supplies where low saturation voltage and fast switching are required. The Trench Field Stop structure gives it a good trade-off between Vce(on) and switching losses, making it suitable for hard-switching topologies up to several tens of kilohertz.
The 175 °C Tj(max) is a common rating for Trench Field Stop IGBTs and allows the device to run hotter than older planar types, but the designer must still ensure the junction temperature stays within limits under worst-case load and ambient conditions.
For new designs, this part is a safe selection with no imminent obsolescence risk.
