= 6.0 - (0.04 x (55 – 22)) = 4.68W
For optimum heatsinking, metal-filled through (Source) via holes should be used directly below the central
metallized ground pad on the bottom of the package.
Note on Thermal Resistivity:
The nominal value of 25
°
C/W is measured with the package mounted on a large
heatsink with thermal compound to ensure adequate (unsoldered) contact. The package temperature is referred to
the Source leads.
HANDLING PRECAUTIONS
To avoid damage to the devices care should be exercised during handling. Proper Electrostatic
Discharge (ESD) precautions should be observed at all stages of storage, handling, assembly, and
testing. This product has be tested to Class 1A (> 250V but < 500V) using JESD22 A114, Human
Body Model, and to Class A, (< 200V) using JESD22 A115, Machine Model.
