AOSMD AO4466

AO4466
30V N-Channel MOSFET
General Description
Product Summary
The AO4466 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. The source leads are separated to allow
a Kelvin connection to the source, which may be
used to bypass the source inductance.

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 junction to ambient thermal resistance rating.
G: L=100uH, VDD=0V, RG=0Ω, rated VDS=30V and VGS=10V
