60 V, 40 A N-channel MOSFET in D-PAK — STripFET F7
The low gate charge of 25 nC at 10 V keeps switching losses in check for DC-DC converters and motor-drive bridges.
8 mOhm Rds(on) — what it means for conduction loss
That translates to roughly 3.2 W conduction loss at 20 A — manageable with the 100 W power-dissipation ceiling and the TO-252 tab soldered to a decent copper area.
With 25 nC total gate charge at 10 V and 1600 pF input capacitance at 30 V Vds, the STD80N6F7 switches fast enough for 100–200 kHz hard-switched converters without excessive driver losses. The low Qg reduces the burden on the gate-drive IC and keeps the Miller plateau narrow, which helps with EMI control. For a 500 kHz or higher design, you would want a part with even lower capacitance, but for most automotive and industrial 60 V rails this is a solid fit.
The 175°C limit is the junction, not the case — the TO-252 package's thermal resistance means you need to derate the 40 A continuous rating above 100°C case temperature. The 100 W power dissipation is at 25°C case; at 100°C case that drops to about 60 W.
