AO8807
Dual P-Channel Enhancement Mode Field Effect Transistor
General Description
Features
The AO8807 uses advanced trench technology to
provide excellent RDS(ON), low gate charge and
operation with gate voltages as low as 1.8V. This
device is suitable for use as a load switch. AO8807
and AO8807L are electrically identical.

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. The power dissipation PD is based on T J(MAX)=150°C, using ≤ 10s junction-to-ambient thermal resistance.
C. Repetitive rating, pulse width limited by junction temperature T J(MAX)=150°C. Ratings are based on low frequency and duty cycles to keep
initialTJ=25°C.
D. The RθJA is the sum of the thermal impedence from junction to lead R θJL and lead to ambient.
E. The static characteristics in Figures 1 to 6 are obtained using <300 µs pulses, duty cycle 0.5% max.
F. These curves are based on the junction-to-ambient thermal impedence which is measured with the device mounted on 1in 2 FR-4 board with
2oz. Copper, assuming a maximum junction temperature of T J(MAX)=150°C. The SOA curve provides a single pulse rating.
