AO4707 P-Channel Enhancement Mode Field Effect Transistor with Schottky Diode General Description The AO4707 uses advanced trench technology to provide excellent R DS(ON) and low gate charge. A Schottky diode is provided to facilitate the implementation of non-synchronous DC-DC converters. Standard Product AO8820 is Pb-free (meets ROHS & Sony 259 specifications). AO8820L is a Green Product ordering option. AO8820 and AO8820L are electrically identical.

Copper, in a still air environment with T A =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 R JL 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. E. These tests are performed with the device mounted on 1 in 2 FR-4 board with 2oz. Copper, in a still air environment with T A=25C. The SOA curve provides a single pulse rating. Rev4: August 2005 THIS PRODUCT HAS BEEN DESIGNED AND QUALIFIED FOR THE CONSUMER MARKET.
