AO4456 N-Channel Enhancement Mode Field Effect Transistor General Description The AO4456 uses advanced trench technology with a monolithically integrated Schottky diode to provide excellent RDS(ON),and low gate charge. This device is suitable for use as a low side FET in SMPS, load switching and general purpose applications. Standard Product AO4456 is Pb-free (meets ROHS & Sony 259 specifications). AO4456 is a Green Product ordering option. AO4456 and AO4456 are electrically identical. Features VDS (V) = 30V ID =20A (VGS = 10V) RDS(ON) < 4.6mΩ (VGS = 10V) RDS(ON) < 5.6mΩ (VGS = 4.5V) D S S S G D D D D G S Absolute Maximum Ratings TA=25°C unless otherwise noted Symbol Parameter VDS Drain-Source Voltage VGS Gate-Source Voltage Continuous Drain Current A Pulsed Dr [ ... ]
