AO4404
N-Channel Enhancement Mode Field Effect Transistor
General Description
Features
The AO4404 uses advanced trench technology to
provide excellent RDS(ON), low gate charge and
operation 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.

A: The value of R θJA is measured with the device mounted on 1in2 FR-4 board with 2oz. Copper, in a still air environment with TA=25°C. The value
in any a 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 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 80 µs pulses, duty cycle 0.5% max.
2
E. These tests are performed with the device mounted on 1 in FR-4 board with 2oz. Copper, in a still air environment with TA=25°C. The SOA
curve provides a single pulse rating.
