STA518

Electrical specifications

9/19

Considering that for the STA518 the Thermal resistance Junction to slug is 1.5°C/W and the

extimated Thermal resistance due to the grease placed between slug and heat sink is

2.3°C/W ( the use of thermal pads for this package is not recommended), the suitable Heat

Sink Rth to be used can be drawn from the following graph Figure 11, where is shown the

Derating Power vs.Tambient for different heatsinkers.
