Gate charge is 40 nC at 10 V, which gives a rough handle on switching losses; the input capacitance is 1000 pF at 25 V Vds. The TO-220 package handles up to 125 W dissipation at the case, but that assumes a well-heatsinked mounting — in a real design, derate based on the junction-to-case thermal resistance. ## Replacement and second-source options For a direct replacement, look for an N-channel MOSFET in a TO-220 package rated at 200 V Vdss and 19 A Id with an Rds(on) at or below 180 mOhm at 10 V gate drive. Several STMicroelectronics PowerMESH parts in the same voltage class may fit, but verify the gate charge and input capacitance match your switching frequency requirements.","metaTitle":"STP19NB20 N-Channel Power MOSFET, 200V 19A, TO-220","metaDescription":"STMicroelectronics STP19NB20 N-channel PowerMESH MOSFET: 200V Vdss, 19A Id, 180mOhm Rds(on) at 10V.
