This moderate gate charge means a gate-driver capable of sourcing 1 A peak can switch the FET in the tens of nanoseconds; the designer should budget gate-drive power as Qg × Vgs × fsw for the target frequency. ## Package and mounting — D²PAK (TO-263) surface mount The STB170NF04 is supplied in the D²PAK (TO-263) surface-mount package, a 2-lead plus tab design.","metaTitle":"STB170NF04 N-Channel MOSFET, 40 V, 80 A, 5 mOhm, D²PAK","metaDescription":"STB170NF04 N-channel MOSFET from STripFET™ II series: 40 V Vdss, 80 A continuous drain, 5 mOhm Rds(on) at 10 V, D²PAK package.
