8. Thermal Characteristics
The following table displays the thermal characteristics of various packages:
The Junction Temperature θj, can be calculated using the following equation: θj = P*θJa + θa
where,
P = Power
θJa = Junction to Ambient Temperature (θJc + θCa)
θa = Ambient Temperature (70 C)
The Case Temperature θc, can be calculated using the following equation: θc = P*θCa + θa
where,
P = Power
θCa = Case to Ambient Temperature
θa = Ambient Temperature (70 C)
