THERMAL DATA
P,PB, DD PACKAGE:
Thermal Resistance-Junction to Tab, θ_JT
3.0°C /W
Thermal Resistance-Junction to Ambient, θ_JA
45°C /W
Junction Temperature Calculation: TJ = TA + (PD × θ JA). The θJA numbers are guidelines for the thermal performance of the device/pc-board
system. All of the above assume no ambient airflow.
