1200 V / 30 A TrenchStop IGBT for power conversion
The Infineon IGW15N120H3FKSA1 is a Trench Field Stop IGBT rated at 1200 V collector-emitter breakdown and 30 A continuous collector current, with a 60 A pulsed capability. It is housed in a TO-247-3 through-hole package (PG-TO247-3-1) and operates over a -40°C to 175°C junction temperature range. Typical applications include motor drives, uninterruptible power supplies, solar inverters, and welding equipment — any medium-frequency switched-mode power stage requiring a 1200 V blocking voltage with low conduction loss.
Conduction and switching losses — the numbers that matter
Vce(on) is 2.4 V maximum at 15 V gate drive and 15 A collector current — the conduction loss floor at that operating point. The total switching energy is 1.55 mJ under the test condition of 600 V, 15 A, 35 Ohm gate resistance, and 15 V gate drive. Gate charge is 75 nC total, which at a 50 kHz switching frequency draws roughly 3.75 mA from the gate driver — well within the capability of most standard IGBT driver ICs. Turn-on delay is 21 ns, turn-off delay 260 ns at 25°C.
It is ROHS3 compliant.
