The STMicroelectronics STGP19NC60KD is a 600 V, 35 A IGBT from the PowerMESH™ series, housed in a through-hole TO-220-3 package. The 600 V collector-emitter breakdown and 35 A continuous collector current set the operating envelope; the 125 W maximum power dissipation defines the thermal budget. The 55 nC gate charge is moderate — a standard gate driver IC can handle it without excessive drive current. The 31 ns reverse recovery time of the internal diode helps keep switching losses in check in hard-switched topologies.
The TO-220 package with through-hole mounting is a workhorse for point-of-load switching stages where board-level heatsinking or a clip-on heatsink is practical.
