800 V，150°C 8H高温三端双向可控硅
意法半导体的8H三端双向可控硅是具有全电力线能力的高压（800 V）开关，专为热量密集型重负荷应用而设计。由于额定结温最高可达150℃，对不利的主电源EMC环境具有较高免疫力，非常适合在越来越紧凑的模块中驱动条件苛刻的负载。
8H和6H三端双向可控硅的最高结温为150°C，特别适用于高温环境和需要高功率密度的PCB设计。意法半导体提供两种不同的系列，600 V 6H系列和800 V 8H系列三端双向可控硅，最大电流为50 A，具有标准或逻辑级栅极灵敏度。均采用D²PAK、I²PAK和TO-220(I)封装。
说得更确切些，从230 V单相电源到400 V三相电源，意法半导体的8H三端双向可控硅的设计用途是作为交流电源开关，用于热水器、工业自动化、暖通空调、卷帘和建筑照明控制单元。这些三端双向可控硅具有snubberless™瞬态电压耐受性能，适应能力强，能够在交流联网应用中常见的EMI干扰和不利的电网环境下可靠地开关。
由于泄漏电流低且稳定，瞬态电流开关能力是额定电流的两倍，电流范围为8 - 30 A的8H三端双向可控硅确保优异的开关能力。8H三端双向可控硅可采用陶瓷绝缘TO-220AB封装、D2PAK封装或传统的TO-220AB包装，结温(TJ)最高可达150℃，因此设计人员可以减小解决方案中散热器的尺寸。作为一种硅半导体和固态解决方案，该系列相比传统继电器具有众多优点，包括无火花和无老化开关特性。
