| AO4803 Dual P-Channel Enhancement Mode Field Effect Transistor General Description The AO4803 uses advanced trench technology to provide excellent RDS(ON) with low gate charge. This device is suitable for use as a load switch or in PWM applications. Standard Product AO4803 is Pb-free (meets ROHS & Sony 259 specifications). AO4803L is a Green Product ordering option. AO4803 and AO4803L are electrically identical. Features VDS (V) = -30V ID = -5 A (VGS = -10V) RDS(ON) < 52m (VGS = -10V) RDS(ON) < 87m (VGS = -4.5V) SOIC-8 Top View S2 G2 S1 G1 1 2 3 4 8 7 6 5 D2 D2 D1 D1 D1 D2 G1 S1 G2 S2 Absolute Maximum Ratings TA=25C unless otherwise noted Parameter Symbol VDS Drain-Source Voltage VGS Gate-Source Voltage Continuous Drain Current A Pulsed Drain Current Power Dissipation A B Maximum -30 20 -5 -4.2 -20 2 1.4 -55 to 150 Units V V A 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 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 6,12,14 are obtained using 80 s pulses, duty cycle 0.5% max. 2 E. These tests are performed with the device mounted on 1 in FR-4 board with 2oz. Copper, in a still air environment with TA=25C. The SOA curve provides a single pulse rating. Rev5: August 2005 THIS PRODUCT HAS BEEN DESIGNED AND QUALIFIED FOR THE CONSUMER MARKET.
