electrical characteristics (t j =25c unless otherwise noted) note 1: based on thermal dissipation from junction to ambient while mounted on a 1" x 1" pcb with optimized layout. a 5 second pulse on a 1" x 1" pcb approximates testing a device mounted on a large multi-layer pcb as in most applications. r jf + r fa = r ja where the foot thermal reference is defined as the normal solder mounting surface of the device's leads. r jf is guaranteed by design, howev- er r ca is determined by the pcb design. actual maximum continuous current is limited by the application's design. note 2: pulse test: pulse width = 300 s note 3: guaranteed by design. not subject to production testing. symbol description conditions min typ max units dc characteristics bv dss drain-source breakdown voltage v gs =0v, i d =250a 30 v r ds(on) drain-source on-resistance 2 v gs =10v, i d =4.8a 40 50 m ? v gs =4.5v, i d =3.8a 60 80 i d(on) on-state drain current 2 v gs =10v, v ds =5v (pulsed) 24 a v gs(th) gate threshold voltage v gs =v ds , i d =250a 1.0 v i gss gate-body leakage current v gs =20v, v ds =0v 100 na i dss drain source leakage current v gs =0v, v ds =30v 1 a v gs =0v, v ds =30v, t j =70c 5 g fs forward transconductance 2 v ds =5v, i d =4.8a 6 s dynamic characteristics 3 q g total gate charge v ds =15v, r d =3.2 ? , v gs =5v 4.5 nc q gt total gate charge v ds =15v, r d =3.2 ? , v gs =10v 8.5 nc q gs gate-source charge v ds =15v, r d =3.2 ? , v gs =10v 1.5 nc q gd gate-drain charge v ds =15v, r d =3.2 ? , v gs =10v 1.3 nc t d(on) turn-on delay v dd =15v, v gs =10v, r d =3.2 ? , r g =6 ? 12 ns t r turn-on rise time v dd =15v, v gs =10v, r d =3.2 ? , r g =6 ? 11 ns t d(off) turn-off delay v dd =15v, v gs =10v, r d =3.2 ? , r g =6 ? 12 ns t f turn-off fall time v dd =15v, v gs =10v, r d =3.2 ? , r g =6 ? 6ns source-drain diode characteristics v sd source-drain forward voltage 2 v gs =0, i s =4.8a 1.4 v i s continuous diode current 1 1.7 a AAT7128 30v n-channel power mosfet 2 7128.2003.05.0.61
