AO4459 P-Channel Enhancement Mode Field Effect Transistor General Description The AO4459 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 AO4459 is Pb-free (meets ROHS & Sony 259 specifications). AO4459L is a Green Product ordering option. AO4459 and AO4459L are electrically identical . Features VDS (V) = -30V (V GS = -10V) ID = -6.5A RDS(ON) < 46m (VGS = -10V) RDS(ON) < 72m (VGS = -4.5V) SOIC-8 Top View S S S G D D D D D G 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 B TA=25C Power Dissipation A TA=70C Junction and Storage Temperature Range Thermal Characteristics Parameter Maximum Junction-to-Ambient Maximum Junction-to-Ambient Maximum Junction-to-Lead C TA=25C TA=70C ID IDM PD TJ, TSTG Maximum -30 20 -6.5 -5.3 -30 3.1 2 -55 to 150 Units V V A W C Symbol A A t 10s Steady-State Steady-State RJA RJL Typ 33 62 18 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 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 < 300s 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. Rev0 Sept 2006 THIS PRODUCT HAS BEEN DESIGNED AND QUALIFIED FOR THE CONSUMER MARKET.
