我们的T系列三端双向可控硅和6H/8H三端双向可控硅专为高温开关控制和改进性能而设计，非常适合额定电压为600 V或800 V的4至50 A应用。
800 V，150°C 8H高温三端双向可控硅
意法半导体的8H三端双向可控硅是专为热密集型重负载应用而设计的高压（800 V）开关，由于其在高达150°C的温度下不受影响的额定性能，具有完整的电力线性能和较高免疫力，非常适合在越来越紧凑的模块中驱动条件苛刻的负载。
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，能够有效地适应交流联网应用中常见的EMI干扰和不稳定的电源环境。
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某些优点，包括无火花和无老化开关特性。
600 V，150°C 6H高温三端双向可控硅
意法半导体的6H高温（600 V）三端双向可控硅具有高浪涌和瞬态电流能力，专为使用交流电源的设备（包括电机、高端家用电器、供热装置、咖啡机和食品加工机）而设计。
栅极电流为10 - 50 mA的版本使其可以通过MCU端口轻松驱动，同时仍然确保符合IEC61000-4-4要求的标准6 kV瞬态电压耐受性能。
由于能够控制高达其额定IT(RMS)4倍的瞬态电流，设计人员可以使用更小的三端双向可控硅完成同样的工作；对感应负载来说，这是一个特别有价值的特性。或通过增强的150°C结温（TJ）减小散热器尺寸，确保体积更小、功能更稳定的电器拥有更高的热余量。
T系列高温（800 V）三端双向可控硅
意法半导体的T系列高温三端双向可控硅专为电器控制中越来越多的AC负载而设计，适用于具有高EMI限制的应用。这些交流电器开关可同时满足对高抗干扰能力和高换向能力的需求，提供经济划算的电源控制解决方案。
该系列的抗干扰能力（dV/dt）和换向能力（dI/dt）更能符合使用需求，即使栅极电流Igt很低。对于所有栅极电流为10 mA的版本来说，最后一个参数是关键，因为它有助于优化电源，并通过在微控制器和可控硅之间接一电阻实现直接驱动能力。
6~25 A 800 V T系列三端双向可控硅（采用35 mA 和800 V栅极额定值）现在可采用D²PAK封装，为更大范围的负载提供改进的EMC抗干扰性和换向。
此外，还提高了瞬时耐冲击电流（ITSM）、抗干扰能力和换向能力之间的均衡度。它领先于普通产品，是目前市面上独一无二的。
