AO3402
N-Channel Enhancement Mode Field Effect Transistor
General Description
Features
The AO3402/L 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. AO3402 and AO3402L are electrically
identical.
VDS (V) = 30V
ID = 4 A (VGS = 10V)
RDS(ON) < 55mΩ (VGS = 10V)
RDS(ON) < 70mΩ (VGS = 4.5V)
RDS(ON) < 110mΩ (VGS = 2.5V)
-RoHS Compliant
-AO3402L is Halogen Free

A: The value of RθJA is measured with the device mounted on 1in2 FR-4 board with 2oz. Copper, in a still air environment with TA =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 RθJA is the sum of the thermal impedence from junction to lead RθJL and lead to ambient.
D. The static characteristics in Figures 1 to 6,12,14 are obtained using <300µs 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=25°C. The
SOA curve provides a single pulse rating.
