AOSMD AO8804

March 2003
AO8804
Common-Drain Dual N-Channel Enhancement Mode Field
Effect Transistor
General Description
Features
The AO8804 uses advanced trench technology to
provide excellent RDS(ON), low gate charge and
operation with gate voltages as low as 1.8V while
retaining a 12V VGS(MAX) rating. It is ESD protected.
This device is suitable for use as a uni-directional or
bi-directional load switch, facilitated by its commondrain configuration.
VDS (V) = 20V
ID = 8A
RDS(ON) < 13mΩ (VGS = 10V)
RDS(ON) < 14mΩ (VGS = 4.5V)
RDS(ON) < 19mΩ (VGS = 2.5V)
RDS(ON) < 27mΩ (VGS = 1.8V)
ESD Rating: 2000V HBM

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 6,12,14 are obtained using 80 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 TA=25°C. The
SOA curve provides a single pulse rating.
