600 V, 80 A TrenchStop IGBT — what it is and where it fits
The Infineon IKW75N60TFKSA1 is a 600 V, 80 A Trench Field Stop IGBT from the TrenchStop series, housed in a through-hole TO-247-3 package. It is designed for hard-switching applications such as motor drives, uninterruptible power supplies, welding inverters, and induction heating where low conduction and switching losses are needed. The 175 °C maximum junction temperature gives thermal headroom for compact heatsink designs.
Key ratings and what they mean for the BOM
Continuous collector current is rated at 80 A, with a pulsed capability of 225 A. This sets the thermal design target: the 428 W maximum power dissipation tells you the heatsink and airflow needed to keep the junction below 175 °C. Gate charge is 470 nC, which means the gate driver must be sized to source and sink that charge fast enough to hit your target switching frequency and deadtime. A standard 15 V gate drive with a few amps of peak current handles it. Switching energy is 4.5 mJ per event at the test condition of 400 V, 75 A, 5 ohm gate resistor, and 15 V gate drive. That figure goes straight into your loss budget for thermal modelling.
Mounting and handling
The TO-247-3 package is through-hole, so it goes into the board and gets soldered or bolted to a heatsink. The PG-TO247-3-1 supplier package code is what you match for the thermal pad and mounting hole pattern.
Lifecycle and compliance
It is ROHS3 compliant, which covers the current EU RoHS exemption list.
