6.10 典型特性
每个 VIN 下的最大建议平均功率安全工作区面积 (SOA) 由 1.5W 限制（虚线）的较低值和该输入电压下的相应热降额曲线（实线）决定。不建议环境温度高于 125oC。热降额功率通过评估板获得，该评估板与“布局示例”部分中所示的 EVM 类似。Tshut 表示初级侧过热关断上升阈值。如“电气特性”表中所示，典型 Tshut 值为 160oC，最小 Tshut 值为 150oC。下面提供了 Tshut = 160oC 和 150oC 时的 SOA 降额曲线。对四种常见 VDD-VEE 设置（15V、18V、22V 和 25V）下的 SOA 曲线进行了表征。在每个 SOA 曲线中，输入电压范围为 9V 至 18V。为了表示 Tshut = 150oC 时的最坏情况，测试在一个屏蔽盒中进行，以阻断热处理室中的循环空气。
