Maximum power dissipation is 48 W at the case, but derating above 25°C is aggressive; a real design budgets for the thermal resistance of the heatsink interface.","metaTitle":"IRF520NPBF HEXFET N-Channel MOSFET, 100 V, 9.7 A, TO-220AB","metaDescription":"IRF520NPBF N-channel HEXFET MOSFET: 100 V Vdss, 9.7 A continuous drain, 200 mOhm Rds(on) at 10 V.
