AO3400A
N-Channel Enhancement Mode Field Effect Transistor
General Description
The AO3400A uses advanced trench technology to
provide excellent RDS(ON) and low gate charge. This
device is suitable for use as a load switch or in PWM
applications. Standard Product AO3400A is
Pb-free (meets ROHS & Sony 259 specifications).

A: The value of RθJA 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.
B: Repetitive rating, pulse width limited by junction temperature T J(MAX)=150°C.
8.5
C. The RθJA is the sum of the thermal impedence from junction to lead R θJL and lead to ambient.
0.0
D. The static characteristics in Figures 1 to 6 are obtained using <300 us pulses, duty cycle 0.5% max. 40
A
E. These tests are performed with the device mounted on 1 in 2 FR-4 board with 2oz. Copper#, Din IaVs/t0il!l air environment with T A=25°C. The SOA
curve provides a single pulse rating.
F: The current rating is based on the t ≤ 10s thermal resistance rating.
