Note:
1. ÎJA : Thermal Resistance-Junction to Ambient, DF: Derating factor, PO: Power consumption.
Junction Temperature Calculation: TJ = TA + (PD x ÎJA ), PO = DF x (TJ â TA)
The ÎJA numbers are guidelines for the thermal performance of the device/PC-board system.
All of the above assume no ambient airflow.
2. ÎJT : Thermal Resistance-Junction to Ambient, TC: case (Tab) temperature, TJ = TC + (PD x ÎJA )
