| AO6702 N-Channel Enhancement Mode Field Effect Transistor with Schottky Diode General Description The AO6702 uses advanced trench technology to provide excellent R DS(ON) and low gate charge. A Schottky diode is provided to facilitate the implementation of a bidirectional blocking switch, or for DC-DC conversion applications. Standard Product AO6702 is Pb-free (meets ROHS & Sony 259 specifications). AO6702L is a Green Product ordering option. AO6702 and AO6702L are electrically identical.

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. Rev3: August 2005 THIS PRODUCT HAS BEEN DESIGNED AND QUALIFIED FOR THE CONSUMER MARKET.
