AOSMD AOD488

AOD488
N-Channel Enhancement Mode Field Effect Transistor
General Description
Features
The AOD488 uses advanced trench technology and
design to provide excellent R DS(ON) with low gate
charge. This device is suitable for use in PWM, load
switching and general purpose applications.
Standard Product AOD488 is Pb-free (meets ROHS
& Sony 259 specifications). AOD488L is a Green
Product ordering option. AOD488 and AOD488L are
electrically identical.

A: The value of R qJA 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 thJA 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.
D. The R qJA is the sum of the thermal impedence from junction to case R qJC and case to ambient.
E. The static characteristics in Figures 1 to 6 are obtained using <300 ms 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)=175 °C.
G.These tests are performed with the device mounted on 1 in 2 FR-4 board with 2oz. Copper, in a still air environment with TA=25 °C. The SOA
curve provides a single pulse rating.
