Feb 2003
AO9926
Dual N-Channel Enhancement Mode Field Effect Transistor
General Description
Features
The AO9926 uses advanced trench technology to
provide excellent RDS(ON) and low gate charge. They
offer operation over a wide gate drive range from 1.8V
to 8V. The two devices may be used individually, in
parallel or to form a bidirectional blocking switch.
VDS (V) = 20V
ID = 5A
RDS(ON) < 50mΩ (VGS = 4.5V)
RDS(ON) < 65mΩ (VGS = 2.5V)

A: The value of R θJA is measured with the device mounted on 1in 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.
