标准三端双向可控硅开关是一种通用AC电源开关，采用简单的小电流栅极驱动器。它们是一种具有无火花和无老化特性的半导体器件，适于各种以市电为电源的电器。栅极简单的相位角滞后点火让我们能够轻松调节照明亮度和通用电机的速度。
无缓冲器双向开关三极管特别适于提高三象限和感应负载设计的关断能力。这种器件的最大反向电压为 800 V，最大电流 40 A。ST 提供透孔及 SMD 成套产品封装：TO-92、SOT-223、DPAK、IPAK、TO-202-3、D²PAK、I²PAK、ISOWATT-220、TO- 220(I)、RD-91、 TOP-3。
T系列是无缓冲三端双向可控硅开关系列的最新产品，增强了给定额定电流下的整流转换。给定额定电流下的抗扰度也提高了5倍之多。
