Product details

600 V, 80 A TrenchStop — the power-stage workhorse

The IKW40N60H3FKSA1: It is designed for hard-switching applications such as motor drives, UPS inverters, and welding machines where conduction and switching losses need to balance across the load range. The test condition of 400 V, 40 A, 7.9 Ohm gate resistor, and 15 V gate drive gives the switching energy of 1.68 mJ.

Gate drive budget: 223 nC Qg

Total gate charge is 223 nC. The turn-on delay is 19 ns and turn-off delay 197 ns at 25 °C; the asymmetry means dead-time needs to be set for the longer off-delay plus margin. The reverse recovery time of the internal diode is 124 ns.

Thermal and mounting — TO-247-3 reality

Maximum power dissipation is 306 W, and the junction temperature range is -40 to 175 °C. Through-hole mounting with a screw torque on the tab is standard.

Frequently asked questions

What is the Vce(on) for IKW40N60H3FKSA1 at 40 A?

The maximum Vce(on) is 2.4 V at 15 V gate drive and 40 A collector current, tested at 400 V bus and 25 °C junction. This is the conduction-loss figure to use in your thermal model.

What is the gate charge (Qg) of IKW40N60H3FKSA1?

Total gate charge is 223 nC. This determines the average gate-drive current and the peak current capability required from the driver at your switching frequency.

Does IKW40N60H3FKSA1 require a heatsink?

Yes — with a maximum power dissipation of 306 W and a 175 °C junction temperature limit, a heatsink is required for any continuous operation above a few amps. The TO-247-3 package's collector tab is electrically live, so use an insulating pad if the heatsink is grounded.
