8. Thermal characteristics
[1] Tsp is the temperature at the solder point of the collector lead.
Tsp has the following relation to the ambient temperature Tamb:
Tsp =T
amb +PRth(sp-a)
With P being the power dissipation and Rth(sp-a) being the thermal resistance between the solder point and
ambient. Rth(sp-a) is determined by the heat transfer properties in the application.
The heat transfer properties are set by the application board materials, the board layout and the
environment e.g. housing.
