500 V blocking in a DPAK footprint
The STD12N50M2: The 380 mOhm maximum on-resistance at 5 A, 10 V gate drive keeps conduction losses manageable in a DPAK package that dissipates up to 85 W.
Switching and drive budget
Gate charge totals 15 nC at 10 V, so a typical gate driver sourcing 1 A can switch the FET in about 15 ns — fast enough for 100 kHz hard-switched converters without excessive cross-conduction. Input capacitance is 550 pF at 100 V drain bias, which sets the Miller plateau charge and the switching loss in a half-bridge leg.
Thermal and mechanical fit
Housed in a TO-252 (DPAK) surface-mount package, the part suits automated pick-and-place assembly.
Sourcing and compliance
STMicroelectronics lists the STD12N50M2 as an active product with no end-of-life notification. It is RoHS3 compliant (2011/65/EU + 2015/863). Available in Tape & Reel (TR) and Cut Tape (CT) options for volume or prototype quantities.
