Package thermal characteristics
A thermal resistance of 25 °C per Watt can be achieved using a ground copper area of
3 x 3 cm, and using 16 vias, on the PCB (see
within the device depends primarily on the supply voltage, load impedance and output
modulation level.
The max estimated dissipated power for the STA333ML is 3 W. This gives, with the
suggested board copper area, a maximum ∆Tj of 75 °C. This gives a safety margin before
the thermal protection intervention is invoked (T
a 50 °C is the maximum ambient temperature.
