The AON7448 is fabricated with SDMOS
TM
trench
technology that combines excellent R
DS(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.

DYNAMIC PARAMETERS
Turn-On Rise Time
Turn-Off DelayTime
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
Power dissipation P
DSM
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 used if the PCB allows it.
B. The power dissipation P
D
is based on T
J(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 T
J(MAX)
=150°C. Ratings are based on low frequency and duty cycles to keep
initial T
J
=25°C.
D. The R
θJA
is the sum of the thermal impedence from junction to case R
θJC
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 T
J(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 in
2
FR-4 board with 2oz. Copper, in a still air environment with T
A
=25°C.
