AOSMD AO4314

AO4314
36V N-Channel MOSFET
General Description
Product Summary
The AO4314 uses trench MOSFET technology that is
uniquely optimized to provide the most efficient high
frequency switching performance.Power losses are
minimized due to an extremely low combination of
RDS(ON) and Crss.In addition,switching behavior is well
controlled with a "Schottky style" soft recovery body
diode.

A. The value of RθJA is measured with the device mounted on 1in2 FR-4 board with 2oz. Copper, in a still air environment with TA =25°C. The
value in any given application depends on the user's specific board design.
B. The power dissipation PD is based on TJ(MAX)=150°C, using ≤ 10s junction-to-ambient thermal resistance.
C. Repetitive rating, pulse width limited by junction temperature TJ(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 RθJL and lead to ambient.
E. The static characteristics in Figures 1 to 6 are obtained using <300µs 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 1in2 FR-4 board with
2oz. Copper, assuming a maximum junction temperature of TJ(MAX)=150°C. The SOA curve provides a single pulse rating.
