3-3. Derating Curve
（Measureing point for case temperature）
（Example of heat sink attatchment）
（Thermal resistance）
①Thermal resisitance： 6.5℃/W ＜Refference value＞
（Junction-Case)
②Thermal resisitance ：Depends on a performance of attached heat sink.
（Case-Atmosphere）

*To keep the case temperature lower than the rating, enough heat-radiation
performance needs to be secured by using an adequate heat sink.
To secure long-term life,use it by the current equal to or less than 360mA .
