It can be used for thermal design of MOSFETs and other components.
Tc = Package temperature
Rthjc = Junction-to-package thermal resistance
Pd = Power dissipation or power rating
Tj = Junction temperature

Si-MOSFET ≤ 150°C: Even at temperatures below 150°C, reliability may be significantly reduced depending on the circumstances.
