120 V, 56 A N-channel — the switching-loss and conduction-loss trade-off
The Infineon IPP147N12N3GXKSA1 is a 120 V, 56 A N-channel MOSFET from the OptiMOS series, in a TO-220-3 through-hole package. Gate charge totals 49 nC at 10 V. Input capacitance is 3220 pF at 60 V Vds.
175 °C junction — thermal headroom for industrial environments
For a motor-drive or PFC stage pulling 56 A at elevated ambient, the 107 W power dissipation ceiling at the case (Tc) means the heatsink must hold the case temperature within the SOA. The TO-220-3 tab is the primary thermal path.
