意法半导体的ACS三端双向可控硅开关或ACST可用作三端双向可控硅开关，并且提高了电压瞬变箝位和吸收能力。'
该器件和系统可成功吸收负载交换以及电源线产生的瞬态，如IEC 61000-4-5所述。 ACST的箝位和消弧功能可以保证为系统与ACST实现安全瞬态性能。因此，无需MOV或缓冲电路即可简化该电路。
这些器件具有高达800V的阻断电压，并且提供标准和逻辑门。
器件采用Fullpack、IPAK、DPAK、D²PAK或I²PAK封装。

Increase immunity and reduce BOM with new 800 V AC switch
Drive loads subjected to high AC line spikes and transients with ST’s new logic-level ACST310; a 3 A, 800 V overvoltage-protected AC switch. Its high-voltage robustness and surge voltage capabilities prove its reliability in low-power appliance systems, and saves PCB space as any MOV protection or RC network can be removed. Available in two package versions, the ACST310-8B in DPAK and the ACST310-8FP in a 2kV UL1557-certified TO-220FPAB, it allows any standard microcontroller to drive resistive or inductive loads up to 250 W.
