The STD78N75F4 carries an official product status of Obsolete. The 75 V Vdss rating places this MOSFET in the 60 V to 80 V class, appropriate for 48 V bus systems, battery-powered equipment, and motor drives with moderate voltage transients. Input capacitance of 5015 pF at 25 V drain-source voltage influences switching losses and driver sizing. ## Package and mounting — DPAK (TO-252-3) The STD78N75F4 is supplied in a DPAK (TO-252-3) surface-mount package with two leads plus a tab (SC-63). The package supports Tape & Reel or Cut Tape shipping formats. The supplier device package is DPAK.","metaTitle":"STD78N75F4 N-Channel MOSFET, 75V 78A DPAK, Obsolete","metaDescription":"STD78N75F4 N-channel MOSFET, 75 V Vdss, 78 A continuous drain, 11 mOhm Rds(on) at 10 V.
