N-Channel MOSFET. AOT280L Datasheet
80V N-Channel MOSFET
The AOT280L/AOB280L 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 RDS(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 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 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 PD is 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 heatsink, 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 in2 FR-4 board with 2oz. Copper, in a still air environment with TA=25°C.
