    Hi Marc,

    The maximum junction temperature is in the datasheet: 150°C

    Ambient temperature is in the datasheet: -40°C to +85°C

    Case temperature is not provided.

    Other values for the PW package, all in °C/W:

    Result- Theta JA-High K (standard datasheet value) 103.5
    Result-Theta JC, top (standard datasheet value) 38.5
    Result-Theta JB (standard datasheet value) 48.5
    Result- Psi JT (standard datasheet value) 3.3
    Result- Psi JB (standard datasheet value) 47.9
