| AO4414 N-Channel Enhancement Mode Field Effect Transistor General Description The AO4414 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. The source leads are separated to allow a Kelvin connection to the source, which may be used to bypass the source inductance. Standard Product AO4414 is Pb-free (meets ROHS & Sony 259 specifications). AO4414L is a Green Product ordering option. AO4414 and AO4414L are electrically identical. Features VDS (V) = 30V ID = 8.5A (VGS = 10V) RDS(ON) < 26m (VGS = 10V) RDS(ON) < 40m (VGS = 4.5V) D S S S G D D D D G SOIC-8 S 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 30 20 8.5 7.1 50 3 2.1 -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 A Maximum Junction-to-Ambient A Maximum Junction-to-Lead C Symbol t 10s Steady-State Steady-State RJA RJL Typ 31 59 16 Max 40 75 24 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 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: June 2005 THIS PRODUCT HAS BEEN DESIGNED AND QUALIFIED FOR THE CONSUMER MARKET.
