AON4701
P-Channel Enhancement Mode Field Effect Transistor
with Schottky Diode
General Description
Features
The AON4701 uses advanced trench technology to provide
excellent R DS(ON) and low gate charge. A Schottky diode is
provided to facilitate the implementation of a bidirectional
blocking switch, or for DC-DC conversion applications.
Standard Product AON4701 is Pb-free (meets ROHS &
Sony 259 specifications).

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 6,12,14 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 T A=25°C. The
SOA curve provides a single pulse rating.
