AON4705L
P-Channel Enhancement Mode Field Effect Transistor
with Schottky Diode
General Description
Features
VDS (V) = -20V
ID = -4A (VGS = -4.5V)
The AON4705L uses advanced trench technology to provide
excellent RDS(ON) and low gate charge. A Schottky diode is
provided to facilitate the implementation of a bidirectional
blocking switch, or for buck converter applications.

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 T = 25°C.
A
The value in any given application depends on the user's specific board design.
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 t ≤ 300µs pulses, duty cycle 0.5% max.
E. These tests are performed with the device mounted on 1 in2 FR-4 board with 2oz. Copper, in a still air environment with T =25°C. The
A
SOA curve provides a single pulse rating.
F. The current rating is based on the t ≤ 10s thermal resistance rating.
