Dual current rating — board vs heatsink
The BSC886N03LS G: Continuous drain current is rated 13 A at 25 °C ambient (Ta) and 65 A at 25 °C case (Tc). The Ta rating reflects the 2.5 W power dissipation limit in free air; the Tc rating of 39 W dissipation requires a thermal pad or heatsink on the PG-TDSON-8 package to reach the silicon limit.
Gate charge and switching speed
Total gate charge Qg is 26 nC at 10 V gate drive, with an input capacitance Ciss of 2100 pF at 15 V drain-source.
Temperature range and package
The PG-TDSON-8 (8-PowerTDFN) surface-mount package has an exposed drain pad for thermal vias to the PCB ground plane.
