AO4842

AO4842 Dual N-Channel Enhancement Mode Field Effect Transistor General Description The AO4842 uses advanced trench technology to provide excellent RDS(ON) and low gate charge. The two MOSFETs make a compact and efficient switch and synchronous rectifier combination for use in buck converters. AO4842 is Pb-free (meets ROHS & Sony 259 specifications). AO4842L is a Green Product ordering option. AO4842 and AO4842L are electrically identical. Features VDS (V) = 30V ID = 7.5A (VGS = 10V) RDS(ON) < 22mΩ (VGS = 10V) RDS(ON) < 35mΩ (VGS = 4.5V) D1 S2 G2 S1 G1 1 2 3 4 8 7 6 5 D2 D2 D1 D1 D2 www.DataSheet4U.com G1 S1 G2 S2 SOIC-8 Absolute Maximum Ratings TA=25°C unless otherwise noted Symbol Parameter VDS Drain-Source Voltage VGS Gate-Source Voltage Continuous Drain Current A Pulsed Drain Current Power Dissipation B Maximum 30 ±20 7.5 6.4 30 2 1.44 -55 to 150 Units V V A TA=25°C TA=70°C TA=25°C TA=70°C ID IDM PD TJ, TSTG W °C Junction and Storage Temperature Range Thermal Characteristics Parameter Maximum Junction-to-Ambient Maximum Junction-to-Ambient Maximum Junction-to-Lead C Symbol A A t ≤ 10s Steady-State Steady-State RθJA RθJL Typ 50 82 41 Max 62.5 110 50 Units °C/W °C/W °C/W Alpha & Omega Semiconductor, Ltd.
