600 V, 60 A TrenchStop IGBT for motor-drive and inverter stages
The Infineon IKW30N60TFKSA1 is a TrenchStop field-stop IGBT in a TO-247-3 through-hole package, rated for 600 V collector-emitter breakdown and 60 A continuous collector current. It targets the main switching element in motor drives, UPS inverters, welding machines, and industrial power supplies where a 400 V to 600 V DC bus is the norm.
Conduction and switching losses — sizing the thermal budget
At the test condition of 400 V bus, 30 A collector, 15 V gate drive, and a 10.6 Ω gate resistor, the typical Vce(sat) is 2.05 V — this sets the on-state conduction loss at 61.5 W for a 100 % duty cycle at 30 A. The total switching energy per cycle is 1.46 mJ, which at a 20 kHz switching frequency adds 29.2 W of switching loss. Combined with the 187 W maximum power dissipation, the designer must verify the junction temperature stays within the -40°C to 175°C range under worst-case load. The 167 nC total gate charge tells the gate-driver designer the average drive current needed: at 20 kHz, a 167 nC gate charge requires 3.3 mA average from the driver; at 40 kHz, 6.7 mA. The turn-on delay is 23 ns and turn-off delay 254 ns at 25°C, with the turn-off tail dominating the switching loss.
Package and mounting — TO-247-3 through-hole
The IKW30N60TFKSA1 ships in the PG-TO247-3-1 package, a standard three-lead TO-247 outline with a 0.110-inch (2.8 mm) centre pin pitch. The through-hole mounting requires a drilled PCB with plated holes; the large tab provides a low-thermal-resistance path to the heatsink. The package is supplied in tube form.
