AO4614B 40V Dual P + N-Channel MOSFET General Description The AO4614B uses advanced trench technology MOSFETs to provide excellent RDS(ON) and low gate charge. The complementary MOSFETs may be used in H-bridge, Inverters and other applications. Product Summary N-Channel VDS (V) = 40V, ID = 6A (VGS=10V) RDS(ON) < 30mΩ (VGS=10V) < 38mΩ (VGS=4.5V) 100% UIS Tested 100% Rg Tested P-Channel -40V -5A (VGS=-10V) < 45mΩ (VGS= -10V) < 63mΩ (VGS= -4.5V) 100% UIS Tested 100% Rg Tested SOIC-8 Top View Bottom View Top View S2 G2 S1 G1 Pin1 1 2 3 4 8 7 6 5 D2 D2 D1 D1 D2 D1 G2 S2 G1 S1 n-channel p-channel Absolute Maximum Ratings TA=25° C unless otherwise noted Parameter Symbol VDS Drain-Source Voltage Gate-Source Voltage Continuous Drain Current A Pulsed Drain Current B Avalanche Curr [ ... ]
