Symbol Parameter Conditions Min Typ Max Unit

Ptot total power dissipation Tsp ≤ 87 °C [1] - - 450 mW

[1] Tsp is the temperature at the solder point of the collector lead.

8 Thermal characteristicsTable 8. Thermal characteristicsSymbol Parameter Conditions Typ Unit

Rth(j-sp) thermal resistance from junction to solder point [1] 140 K/W

[1] Tsp is the temperature at the solder point of the collector lead.

Tsp has the following relation to the ambient temperature Tamb:

Tsp = Tamb + P × Rth(sp-a)

With P being the power dissipation and Rth(sp-a) being the thermal resistance betweenthe solder point and ambient. Rth(sp-a) is determined by the heat transfer properties in theapplication.

The heat transfer properties are set by the application board materials, the board layoutand the environment e.g. housing.
