| Rev 2: Nov 2004 AO4802, AO4802L ( Green Product ) Dual N-Channel Enhancement Mode Field Effect Transistor General Description The AO4802 uses advanced trench technology to provide excellent RDS(ON) and low gate charge. They offer operation over a wide gate drive range from 1.8V to 12V. The two devices may be used individually, in parallel or to form a bidirectional blocking switch. AO4802L ( Green Product ) is offered in a lead-free package. Features VDS (V) = 30V ID = 7A RDS(ON) < 26m (VGS = 10V) RDS(ON) < 30m (VGS = 4.5V) RDS(ON) < 40m (VGS = 2.5V) RDS(ON) < 70m (VGS = 1.8V) D1 S2 G2 S1 G1 D2 D2 D1 D1 D2 1 2 3 4 8 7 6 5 G1 S1 G2 S2 SOIC-8 Absolute Maximum Ratings TA=25C unless otherwise noted Parameter Symbol VDS Drain-Source Voltage Gate-Source Voltage Continuous Drain Current A Pulsed Drain Current Power Dissipation B Maximum 30 12 7 6 40 2 1.44 -55 to 150 Units V V A VGS TA=25C TA=70C TA=25C TA=70C ID IDM PD TJ, TSTG W C Junction and Storage Temperature Range Thermal Characteristics Parameter Maximum Junction-to-Ambient A Maximum Junction-to-Ambient A Maximum Junction-to-Lead C Symbol t 10s Steady-State Steady-State RJA RJL Typ 48 74 35 Max 62.5 110 40 Units C/W C/W C/W Alpha & Omega Semiconductor, Ltd.

Copper, in a still air environment with TA=25C. The value in any a given application depends on the user's specific board design. The current rating is based on the t 10s thermal resistance rating. B: Repetitive rating, pulse width limited by junction temperature. C. The R JA is the sum of the thermal impedence from junction to lead RJL and lead to ambient. D. The static characteristics in Figures 1 to 6 are obtained using 80s pulses, duty cycle 0.5% max. E. These tests are performed with the device mounted on 1 in2 FR-4 board with 2oz. Copper, in a still air environment with TA=25C. The SOA curve provides a single pulse rating. THIS PRODUCT HAS BEEN DESIGNED AND QUALIFIED FOR THE CONSUMER MARKET.
