AO4404B
N-Channel Enhancement Mode Field Effect Transistor
General Description
The AO4404B uses advanced trench technology to
provide excellent RDS(ON), low gate charge and
www.DataSheet4oUp.ceormation with gate voltages as low as 2.5V. 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. Standard Product
AO4404B is Pb-free (meets ROHS & Sony 259
specifications).
Features

A: The value of RθJA 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 RθJL and lead to ambient.
D. The static characteristics in Figures 1 to 6 are obtained using <300µs 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 TA=25°C. The SOA
curve provides a single pulse rating.
F. The current rating is based on the t10s junction to ambient thermal resistance rating.
