AO4826 Dual N-Channel Enhancement Mode Field Effect Transistor General Description The AO4826 uses advanced trench technology to provide excellent RDS(ON) and low gate charge. This device is suitable for use as a load switch or in PWM applications. Standard Product AO4826 is Pb-free (meets ROHS & Sony 259 specifications). AO4826L is a Green Product ordering option. AO4826 and AO4826L are electrically identical. Features VDS (V) = 60V ID = 6.3A (VGS = 10V) RDS(ON) < 25m (VGS = 10V) RDS(ON) < 30m (VGS = 4.5V) D1 S2 G2 S1 G1 1 2 3 4 8 7 6 5 D2 D2 D1 D1 G1 G2 S1 D2 SOIC-8 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 B Maximum 60 20 6.3 5 40 2 1.28 -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 50 73 31 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 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. Rev 4 : Aug 2005 THIS PRODUCT HAS BEEN DESIGNED AND QUALIFIED FOR THE CONSUMER MARKET.
