IGW75N60H3
600 V / 75 A TrenchStop H3 IGBT for high-current welding inverters, battery chargers and UPS power stages.
600 V / 75 A TrenchStop H3 IGBT for high-current power conversion, welding inverters and UPS power stages with low saturation voltage and fast switching.
FAE Professional Review
The IGW75N60H3 covers the workhorse 600 V / 75 A class used across welding, UPS and battery chargers. Its low Vce(sat) keeps conduction losses manageable at high duty cycles, while the fast diode handles hard-switching transitions. For cost-sensitive builds, compare it against the reverse-conducting IHW75N60R, which removes the external freewheeling diode.

Frequently Asked Questions
What is the IGW75N60H3 best used for?
It is a 600 V / 75 A TrenchStop H3 IGBT for high-current power conversion such as welding inverters, battery chargers and UPS power stages. Low Vce(sat) keeps conduction loss manageable at high duty cycles.
Choose the 1200 V class only if your DC link needs it.
Do I need an external freewheeling diode?
The standard device relies on an external freewheeling diode sized for your reverse recovery. If board space and cost dominate, a reverse-conducting variant integrates the diode.
Our FAE team can recommend a matched diode for your topology.
How do I manage heat at 75 A?
At this current, thermal design dominates. Use a proven TO-247 mounting method with low thermal interface resistance and verify junction temperature at maximum duty cycle and ambient.
We can review your heatsink and airflow assumptions.
How does it compare with the IKW40N120H3?
The IGW75N60H3 delivers 600 V / 75 A for higher-current, lower-voltage work, while the IKW40N120H3 covers 1200 V / 40 A for higher DC-link drives. The choice is set by bus voltage and current, not brand.
Compare the two on this page before deciding.
What gate-drive settings suit hard-switched operation?
Start with the datasheet gate resistor range, then tune for acceptable dv/dt and EMI. Keep the gate loop short and separate the power and signal grounds.
Our application note details gate-resistor selection and dead-time.
Is the part genuine and in stock?
The IGW75N60H3 is normally available from regional stock with the import declaration, certificate of origin and RoHS file included. The datasheet downloads from this page.
