General Description
The AO4603 uses advanced trench technology
MOSFETs to provide excellent R
DS(ON)
and low
gate charge. The complementary MOSFETs
may be used to form a level shifted high side
switch, and for a host of other applications.
Standard product AO4603 is Pb-free (meets
ROHS & Sony 259 specifications). AO4603L is
a Green Product ordering option. AO4603 and
AO4603L 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.
