Product details

1200 V Trench Field Stop IGBT in TO-247-3

The STMicroelectronics STGW40H120F2 is a 1200 V, 80 A Trench Field Stop IGBT in a TO-247-3 through-hole package. It is designed for medium-frequency hard-switching applications such as motor drives, uninterruptible power supplies, welding inverters, and solar inverters where low conduction and switching losses are required. The Trench Field Stop structure delivers a saturation voltage of 2.6 V at 15 V gate drive and 40 A, combined with switching energies of 1 mJ (on) and 1.32 mJ (off) under the 600 V, 40 A, 10 Ohm, 15 V test condition.

Pulsed current and ruggedness

The pulsed collector current rating of 160 A (Icm) gives headroom for inrush, start-up, or fault conditions — useful in motor-drive short-circuit withstand or capacitor-charging applications. The standard input type means no integrated gate-emitter clamp or sense emitter; the gate drive must provide proper clamping and protection externally.

The STGW40H120F2 has Active lifecycle status and ROHS3 compliance.

Frequently asked questions

Does STGW40H120F2 require a heat sink?

Yes. At 40 A continuous collector current and 468 W maximum power dissipation, a heatsink is required. The TO-247 case alone cannot dissipate that heat — plan for forced air or a large extruded aluminium heatsink, and verify the thermal impedance in your airflow conditions.

What is the typical application for STGW40H120F2?

Motor drives, uninterruptible power supplies, welding inverters, and solar inverters — any medium-frequency hard-switching power converter operating from a 400 VAC or higher DC bus where 1200 V blocking and 40 A continuous current are needed.
