The AOT266L & AOB266L & AOTF266L uses Trench
MOSFET technology that is uniquely optimized to provide
the most efficient high frequency switching performance.
Both conduction and switching power losses are
minimized due to an extremely low combination of R
DS(ON)
,
Ciss and Coss. This device is ideal for boost converters
and synchronous rectifiers for consumer, telecom,
industrial power supplies and LED backlighting.

A. The value of RθJA is measured with the device mounted on 1in2FR-4 board with 2oz. Copper, in a still air environment with TA=25°C. The
Power dissipation PDSM is based on R θJA 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 175°C may be used if the PCB allows it.
B. The power dissipation PDis based on TJ(MAX)=175°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)=175°
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 impedance 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 impedance which is measured with the device mounted to a large heatsin
k, assuming a
maximum junction temperature of TJ(MAX)=175°C. The SOA curve provides a single pulse rating.
G. The maximum current limited by package.
H. These tests are performed with the device mounted on 1 in2FR-4 board with 2oz. Copper, in a still air environment with TA=25°C.
