The junction-to-air thermal resistance, RθJA, in the Thermal Information table is that of a device installed on a high-K test board for leaded surface-mount packages. Use the following equations to calculate the value for each parameter: TJ = TA + RθJA × P, where P is the power ...

TJ = TA + (θJA × PD) ここで, TA は周囲温度(ºC), PD は消費電力(ワット)です. θJC の値は,外付けヒート・シンクが必要な場合のパッケージ の比較と PCB 設計時の検討用です. 表 40. 熱抵抗 Package Type CP-48-132, 3 θJA θJMA1 23.1 18.4, 17.1 θJC Unit 0.7 °C/...
