At 11 A, that is about 19.6 W dissipated in the channel — the 125 W case-rated power dissipation means the die can handle it with adequate heatsinking, but the 2.8 W ambient rating flags that the board-level thermal design is what limits continuous current in a real enclosure. ## Gate charge and switching — 45 nC at 10 V Total gate charge is 45 nC at 10 V. That is moderate for a 650 V 15 A device — the driver sees about 4.5 mA per 100 kHz of switching frequency from the gate alone. The 1865 pF input capacitance at 100 V confirms the Miller plateau is manageable; a standard 1 A gate driver will switch this part cleanly into the 100–200 kHz range without excessive cross-conduction. Running at 5 V would leave the channel partially enhanced, increasing conduction losses. The ±25 V Vgs max gives margin for gate ringing on a hard-switched half-bridge. ## PowerFlat 8x8 HV — footprint and thermal path The PowerFlat 8x8 HV package is a surface-mount 8-lead VDFN with an exposed die pad on the bottom. The 125 W case-rated power dissipation requires a thermal path through the pad. The package is ROHS3 compliant and surface-mount. For a BOM line, that means no last-time-buy planning needed. The part is ROHS3 compliant.","metaTitle":"STL31N65M5 N-Channel 650 V MOSFET, 162 mOhm, PowerFlat 8x8","metaDescription":"STL31N65M5 N-channel 650 V 15 A MOSFET from STMicroelectronics MDmesh V series. 162 mOhm Rds(on) at 10 V, 45 nC gate charge.
