General Description
The AO4816 uses advanced trench technology to
provide excellent R
DS(ON)
and low gate charge. This
dual device is suitable for use as a load switch or in
PWM applications.
Standard Product AO4816 is Pb-
free (meets ROHS & Sony 259 specifications).
AO4816L is a Green Product ordering option.
AO4816 and AO4816L are electrically identical.

A: The value of R
JA
is measured with the device mounted on 1in
2
FR-4 board with 2oz. Copper, in a still air environment with T
A
=25C. 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
JA
is the sum of the thermal impedence from junction to lead R
JL
and lead to ambient.
D. The static characteristics in Figures 1 to 6 are obtained using 80
s 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
=25C. The SOA curve
provides a single pulse rating.
