The exposed metal tab on the top provides a direct thermal path to a heatsink or chassis; plan for a thermal pad or insulating washer if the tab is at drain potential. Input capacitance (Ciss) is 1265 pF at 25 V drain-source, which influences gate-drive rise time and switching losses — factor it into the gate resistor calculation for the target switching frequency.
