AOSMD AO7417

AO7417
P-Channel Enhancement Mode Field Effect Transistor
General Description
Features
The AO7417/L uses advanced trench technology to
provide excellent RDS(ON), low gate charge and
operation with gate voltages as low as 1.5V, in the
small SOT363 footprint. This device is suitable for
use in buck convertor.
AO7417 and AO7417L 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 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 R θJL and lead to ambient.
D. The static characteristics in Figures 1 to 6 are obtained using 300 µs pulse width, 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 T A=25°C. The SOA
curve provides a single pulse rating.
