Is there no data for transient thermal resistance of Rth (ch-c)?

Latest Updated:12/01/2011

Question:

Only the transient thermal resistance of Rth (ch-a) is described in the data sheets of 8-pin SOP products such as the uPA2756; is there no data available for the transient thermal resistance of Rth (ch-c)?

Answer:

The channel-to-case thermal resistance (Rth (ch-c)) is only prescribed for packages with a structure in which a heat sink is used.
8-pin SOP products such as the uPA2756 do not have a structure in which a heat sink is used, so the channel-to-case thermal resistance (Rth (ch-c)) is not prescribed.
