JL is the thermal resistance between the junction and device lead. To determine the virtual junction temperature (TJ) relative to the device lead
temperature, the following calculations should be used: TJ = PD x R
θ
JL + TL, where PD is the internal power dissipation of the device, and TL is
the device lead temperature at the point of contact to the printed wiring board. R
