AOD256

AOD256 150V N-Channel MOSFET General Description Product Summary The AOD256 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.

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
