1200 V, 80 A TrenchStop IGBT for power conversion stages
The Infineon IHW40N120R5XKSA1 is a 1200 V, 80 A Trench Field Stop IGBT in the TrenchStop series, housed in a PG-TO247-3 through-hole package. It is designed for hard-switching applications such as motor drives, uninterruptible power supplies, and induction heating where conduction and switching losses drive the thermal budget. The 1.85 V typical Vce(on) at 15 V gate drive and 40 A collector current sets the conduction loss baseline, while the 1.6 mJ turn-off energy at 600 V, 40 A, 10 Ω gate resistor defines the switching loss per cycle.
Conduction and switching loss at the operating point
The on-state voltage of 1.85 V at 15 V gate drive and 40 A sets the conduction loss baseline. The turn-off energy of 1.6 mJ at 600 V, 40 A, 10 Ω gate resistor defines the switching loss per cycle.
175°C junction rating — thermal margin for sealed enclosures
The -40°C to 175°C operating junction temperature range is the industrial-grade rating. The 175°C Tj(max) allows headroom above the typical 150°C limit found in many IGBTs, which matters when the device runs in a sealed motor-drive enclosure or a PFC stage with limited airflow. The 394 W maximum power dissipation assumes the case is held at 25°C — real-world derating follows the thermal resistance of the chosen heatsink and interface material.
Active lifecycle — no LTB risk for new designs
The IHW40N120R5XKSA1 carries an Active product status with ROHS3 compliance. For production BOMs that require a 1200 V, 80 A TrenchStop IGBT in a TO-247-3, this part is a current-production choice with standard distribution availability.
Sourcing and BOM fit
For dual-sourcing or a lower-current BOM variant, the IHW30N120R5XKSA1 shares the same TrenchStop technology, TO-247-3 footprint, and 1.85 V Vce(on) characteristic but at 30 A continuous collector current and 330 W power dissipation — a direct parametric step-down when the load budget allows.
