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.
