600 V N-channel in an isolated full-pack
The STF16N60M2 is a 600 V, 12 A N-channel power MOSFET from ST's MDmesh M2 series, housed in a TO-220FP full-pack through-hole package. It targets offline switched-mode power supplies, PFC stages, and resonant converters where the isolated tab simplifies heatsinking and eliminates the insulating pad.
Conduction and switching losses at the operating point
At 12 A continuous drain current the Rds(on) will be higher due to self-heating; the 25 W dissipation ceiling in the TO-220FP package is the practical thermal limit, not the 12 A current rating. Total gate charge is 19 nC at 10 V. Input capacitance is 700 pF at 100 V drain-source.
Full-pack package simplifies thermal design
No insulating pad or washer is needed, which reduces assembly steps and improves thermal contact consistency. The trade-off is higher thermal resistance compared to a standard TO-220 — the 25 W power dissipation limit reflects this. The full-pack construction means the case temperature rises faster than a metal-tab package; derate power dissipation above 25 °C case temperature per the datasheet curve.
It is ROHS3 compliant.
