| AO3404 N-Channel Enhancement Mode Field Effect Transistor General Description The AO3404 uses advanced trench technology to provide excellent RDS(ON) and low gate charge. This device may be used as a load switch or in PWM applications. Standard Product AO3404 is Pb-free (meets ROHS & Sony 259 specifications). AO3404L is a Green Product ordering option. AO3404 and AO3404L are electrically identical. Features VDS (V) = 30V ID = 5.8A (VGS = 10V) RDS(ON) < 28m (VGS = 10V) RDS(ON) < 43m (VGS = 4.5V) TO-236 (SOT-23) Top View G D S G D S Absolute Maximum Ratings T A=25C unless otherwise noted Parameter Symbol VDS Drain-Source Voltage VGS Gate-Source Voltage Continuous Drain A Current Pulsed Drain Current Power Dissipation B Maximum 30 20 5.8 4.9 20 1.4 1 -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 Maximum Junction-to-Ambient Maximum Junction-to-Lead C Symbol A A t 10s Steady-State Steady-State RJA RJL Typ 65 85 43 Max 90 125 60 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 80 s 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 5 : July 2005 THIS PRODUCT HAS BEEN DESIGNED AND QUALIFIED FOR THE CONSUMER MARKET.
