General Description
The AOU460 uses advanced trench technology and
design to provide excellent R
DS(ON)
with low gate
charge. This device is suitable for use in PWM, load
switching and general purpose applications. Standard
Product AOU460 is Pb-free (meets ROHS & Sony
259 specifications). AOU460L is a Green Product
ordering option. AOU460 and AOU460L are
electrically identical.

A: The value of R
JA
is measured with the device in a still air environment with T
A
=25C.
B. The power dissipation P
D
is based on T
J(MAX)
=175C, using junction-to-case thermal resistance, and is more useful in setting the upper
dissipation limit for cases where additional heatsinking is used.
C: Repetitive rating, pulse width limited by junction temperature T
J(MAX)
=175C.
D. The R
JA
is the sum of the thermal impedence from junction to case R
JC
and case to ambient.
E. The static characteristics in Figures 1 to 6 are obtained using <300
s pulses, duty cycle 0.5% max.
F. These curves are based on the junction-to-case thermal impedence which is measured with the device mounted to a large heatsink, assuming a
maximum junction temperature of T
J(MAX)
=175C.
G. The maximum current rating is limited by bond-wires.
