AO3401 P-Channel Enhancement Mode Field Effect Transistor General Description Features The AO3401 uses advanced trench technology to provide excellent RDS(ON), low gate charge and operation with gate voltages as low as 2.5V. This device is suitable for use as a load switch or in PWM applications. Standard product AO3401 is Pb-free (meets ROHS & Sony 259 specifications). AO3401L is a Green Product ordering option. AO3401 and AO3401L 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 6,12,14 are obtained using 80 s pulses, duty cycle 0.5% max. 2 E. These tests are performed with the device mounted on 1 in FR-4 board with 2oz. Copper, in a still air environment with TA=25C. The SOA curve provides a single pulse rating. THIS PRODUCT HAS BEEN DESIGNED AND QUALIFIED FOR THE CONSUMER MARKET.
