Notes: 1. Value under Ta ≤ 77°C. If Ta is greater, 8.3 mW/°C derating occurs.
2. Allowable temperature of IC junction part, Tj (max), is as shown below.
Tj (max) = θj–a•Pc (max)+Ta
(θj-a is thermal resistance value during mounting, and Pc (max) is the maximum value of IC power
dissipation.)
Therefore, to keep Tj (max) ≤ 125°C, wiring density and board material must be selected according to the
board thermal conductivity ratio shown below.
Be careful that the value of Pc (max) does not exceed that PT.
