SGTP40V120FDB2P7
1200 V / 40 A Silan trench field-stop discrete IGBT in TO-247, 1.9 V VCE(sat), for solar, PFC and UPS stages.
The SGTP40V120FDB2P7 is a 1200 V / 40 A Silan discrete IGBT in the TO-247 package, with a typical saturation voltage of 1.9 V and a trench field-stop chip designed for photovoltaic, UPS, SMPS and power-factor-correction applications. Its 1200 V blocking voltage gives the margin a 380 to 480 V AC converter needs after rectification and switching overshoot, so it suits higher-voltage PFC stages, solar boost and inverter circuits and industrial power supplies. The low saturation voltage keeps conduction loss small at the 40 A rating, and the trench field-stop structure balances switching loss and ruggedness. As a single device it gives full design freedom over the gate drive and the freewheeling path, and the TO-247 footprint mounts on standard heatsinks. Every device is factory-traceable and ships with import declaration, certificate of origin and RoHS documentation. Designers should confirm the gate drive, the freewheeling diode and the 1200 V thermal design before committing the layout. BeiLuo holds this device in regional stock and our FAE team supports selection, gate-drive tuning and thermal validation.
FAE Professional Review
The SGTP40V120FDB2P7 pairs a 1200 V class with a low 1.9 V saturation voltage, which is exactly what a solar boost or high-voltage PFC stage wants. The trench field-stop chip switches cleanly and the TO-247 body is easy to cool. Keep the commutation loop tight and it is a very predictable device.

Frequently Asked Questions
What projects suit the SGTP40V120FDB2P7?
It fits 1200 V converters that run from a 400 V class bus, including photovoltaic boost and inverter stages, high-voltage power-factor correction and UPS or SMPS power stages. The 1.9 V saturation voltage keeps conduction loss low.
For a 220 V bus, the 600 V SGT40N60NPFDPN is more economical.
How do I control overshoot at 1200 V?
At 1200 V the margin matters, so keep the commutation loop tight and tune the gate resistor to limit dv/dt and overshoot. Measure turn-off overvoltage at the device terminals, not at the bus.
Our FAE team can review your layout.
