General Description
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.

DYNAMIC PARAMETERS
A: The value of R θJA is measured with the device mounted on 1in
2 FR-4 board with 2oz. Copper, in a still air environment with T
A =25°C. 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 θJA is the sum of the thermal impedence from junction to lead R
θJL and lead to ambient.
D. The static characteristics in Figures 1 to 6,12,14 are obtained using 80 µs 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=25°C. The
SOA curve provides a single pulse rating.
