AO3434
N-Channel Enhancement Mode Field Effect Transistor
General Description
Features
The AO3434 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. It is ESD protected.
Standard Product AO3434 is Pb-free (meets
ROHS & Sony 259 specifications).

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.
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.
F.The current rating is based on the t≤10s thermal resistance rating.
