THERMAL DATA
Thermal Resistance from Junction to Ambient, θJA
TBD °C /W
Junction Temperature Calculation: TJ = TA + (PD × θJA).
The θJA numbers are guidelines for the thermal performance of the device/pc-board system.
Connect the ground pin to ground using a large pad or ground plane for better heat dissipation.
All of the above assume no ambient airflow.
Maximum Power Calculation:
TJ(MAX) – TA(MAX)
PD(MAX)
=
θJA
TJ(OC):
Maximum recommended junction temperature
TA(OC):
Ambient temperature of the application
θJA(OC /W):
Junction-to-Ambient thermal resistance of the package, and other heat dissipating materials.
