40 V, 85 A N-channel — conduction loss floor at 2.4 mOhm
Gate charge totals 138 nC at 10 V, which determines the driver current needed for the target switching frequency.
Thermal and package — 104 W through the exposed pad
The 0.50 mm pitch of the PQFN-8 demands a solder-paste stencil aperture sized for the pad geometry — a standard reflow profile for lead-free solder applies.
Gate drive and switching — not a logic-level part
The gate threshold voltage is 3.9 V maximum at 100 µA drain current, and the drive voltage range for achieving minimum on-resistance is 6 V to 10 V. This is not a logic-level MOSFET — a 3.3 V gate signal will not fully enhance the channel. The input capacitance is 4574 pF at 25 V drain-source, which together with the 138 nC gate charge means the gate driver must supply several amperes of peak current for fast switching edges in a 100 kHz+ converter.
