AO3422
N-Channel Enhancement Mode Field Effect Transistor
General Description
Features
The AO3422 uses advanced trench technology to
VDS (V) = 55V
provide excellent RDS(ON) and low gate charge. It offers
operation over a wide gate drive range from 2.5V to
12V. This device is suitable for use as a load switch.

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 are obtained using <300 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.
