That 5:1 ratio tells you the PG-TDSON-8 package can move heat to a heatsink or board copper plane, but without it the junction-to-ambient thermal resistance limits you to about 2.5 W dissipation. The 57 W power dissipation at Tc is real only if the PCB copper area under the drain tab matches the Infineon layout recommendation. ## 41 nC gate charge — what it costs to switch Gate charge Qg is 41 nC typical at 10 V. In a 500 kHz buck converter the gate drive loss is Qg × Vgs × fsw, about 0.2 W — manageable from a 1 A gate driver. The 3200 pF input capacitance at 15 V drain bias means the driver sees a capacitive load that slows the switching edge if the gate loop inductance is not kept tight. The 4.5 V drive voltage option lets you run from a 5 V logic rail, but the Rds(on) will rise above the 3.8 mOhm minimum — the 10 V drive is where the datasheet guarantees the lowest resistance. ROHS3 compliant. No official successor or cross-reference is published — the part is still in the Infineon portfolio for new designs.","metaTitle":"BSC883N03MSG N-Channel Power MOSFET, 34 V, 3.8 mOhm","metaDescription":"Infineon BSC883N03MSG OptiMOS 3M N-channel MOSFET, 34 Vdss, 3.8 mOhm Rds(on) at 10 V, 98 A continuous drain at Tc.
