Application Information (Cont.)
Power Dissipation and Junction Temperature
The low on-resistance of the internal MOSFET allows the small surface-mount packages to pass large current. Using the maximum operating
ambient temperature (TA) and RDS(ON), the power dissipation can be calculated by:
PD = RDS(ON)× I²
Finally, calculate the junction temperature:
TJ = PD x RθJA + TA
Where:
TA = Ambient temperature °C
RθJA = Thermal resistance
PD = Total power dissipation
