AON7450
100V N-Channel MOSFET
SDMOS TM
General Description
Product Summary
The AON7450 is fabricated with SDMOSTM trench
technology that combines excellent RDS(ON) with low gate
charge and low Qrr.The result is outstanding efficiency
with controlled switching behavior. This universal
technology is well suited for PWM, load switching and
general purpose applications.

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
Power dissipation PDSM is based on R θJA t ≤ 10s value and the maximum allowed junction temperature of 150°C. The value in any given
application depends on the user's specific board design, and the maximum temperature of 150°C may be u sed if the PCB allows it.
B. The power dissipation PD is based on TJ(MAX)=150°C, using junction-to-case thermal resistance, and is more useful in setting the upper
dissipation limit for cases where additional heatsinking is used.
C. Repetitive rating, pulse width limited by junction temperature TJ(MAX)=150°C. Ratings are based on low frequency and duty cycles to keep
initial TJ =25°C.
D. The RθJA is the sum of the thermal impedence from junction to case RθJC and case 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-case thermal impedence which is measured with the device mounted to a large heatsink,
assuming a maximum junction temperature of TJ(MAX)=150°C. The SOA curve provides a single pulse ratin g.
G. The maximum current rating is package limited.
H. These tests are performed with the device mounted on 1 in2 FR-4 board with 2oz. Copper, in a still air environment with TA=25°C.
