AO3420
N-Channel Enhancement Mode Field Effect Transistor
General Description
Features
The AO3420 uses advanced trench technology to
provide excellent RDS(ON), low gate charge and
operation with gate voltages as low as 1.8V while
retaining a 12V VGS(MAX) rating. This device is
suitable for use as a uni-directional or bi-directional
load switch. Standard Product AO3420 is Pb-free
(meets ROHS & Sony 259 specifications). AO3420L
is a Green Product ordering option. AO3420 and
AO3420L are electrically identical.

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 80µs 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.
