Key Features
- 1200 V collector-emitter breakdown voltage enabling direct use in 600 V AC line-connected power conversion stages
- 15 A continuous collector current with trench gate field-stop technology reducing conduction losses at elevated temperatures
- High-speed H-series optimisation providing fast turn-off with low tail current for 20 kHz to 100 kHz switching designs
- TO-247 through-hole package simplifying heatsink mounting and delivering low thermal resistance for high-power dissipation
Applications
The STGWA15H120F2 is targeted at PFC boost stages, full-bridge DC-DC converters, and UPS inverters operating from rectified 400 V or 600 V DC buses that require a rugged 1200 V switch with fast commutation. Its low switching losses make it competitive in LLC resonant converters running above 50 kHz where turn-on and turn-off energy directly determines efficiency. The device is also deployed in solar micro-inverters and motor-drive output stages where the combination of 1200 V blocking voltage and 15 A current rating fits the typical 1.5 kW to 3 kW power class.

Frequently Asked Questions
What continuous collector current and voltage rating make STGWA15H120F2 suitable for PFC and inverter designs?
The STGWA15H120F2 is rated for 15 A continuous collector current at a 1200 V collector-emitter voltage, which directly supports PFC boost stages and full-bridge inverters connected to 230 V AC mains after rectification. The 1200 V headroom provides more than 2x margin over the 400 V DC bus peak, accommodating line transients and parasitic ringing without additional snubbers.
How does the trench gate field-stop structure in STGWA15H120F2 reduce power losses versus a standard planar IGBT?
The trench gate geometry reduces gate-collector capacitance by approximately 30% compared to planar IGBTs of the same voltage class, lowering switching losses at 20 kHz switching frequency. The field-stop buffer layer truncates the conductivity-modulated drift region, cutting turn-off tail current and reducing turn-off energy to under 0.5 mJ at 15 A, which translates directly to higher efficiency in hard-switching converters.
At what switching frequency can STGWA15H120F2 operate efficiently in a resonant LLC converter design?
The H-series high-speed optimisation allows operation at switching frequencies from 20 kHz to above 100 kHz in zero-voltage-switching LLC resonant topologies, where the soft commutation eliminates most turn-on losses. At 100 kHz with ZVS transitions, measured turn-off energy is typically under 0.3 mJ at 600 V and 15 A, giving efficiency above 98% in a 2 kW LLC stage.
What thermal resistance does the TO-247 package of STGWA15H120F2 offer, and how does that affect heatsink selection?
The TO-247 package provides a junction-to-case thermal resistance of approximately 1.0 K/W, which limits the maximum continuous power dissipation to around 125 W with an adequate heatsink at 25 degrees Celsius ambient. A designer selecting a heatsink for a 2 kW converter with 2% IGBT losses (40 W) would need a heatsink thermal resistance below 1.8 K/W to keep the junction below 150 degrees Celsius.
