600 V, 20 A — the switching-stage workhorse
The STGP10NC60KD is a 600 V, 20 A IGBT from ST's PowerMESH™ series, housed in a TO-220 through-hole package. With a gate charge of 19 nC and switching energies of 55 µJ (on) and 85 µJ (off) at 390 V, 5 A, the part is optimised for hard-switched topologies up to several tens of kHz — typical for PFC stages, induction heating, and motor inverters.
Switching losses and thermal budget
The 19 nC total gate charge keeps the drive current modest — a 1 A gate driver can switch the device in under 20 ns, though the 17 ns/72 ns turn-on/turn-off delay times (Td) at 25 °C set the practical switching speed floor. The 65 W power dissipation ceiling in the TO-220 package means the junction temperature rise must be calculated against the actual switching frequency and load current. The integrated diode's 22 ns reverse recovery time reduces turn-on loss in the complementary switch of a bridge leg, a common pain point in hard-switched inverters where diode stored charge otherwise spikes the turn-on current.
The 600 V collector-emitter breakdown voltage provides adequate margin for 400 VDC bus applications (typical in three-phase PFC and motor drives), with headroom for transients up to the device's 30 A pulsed collector rating.
