ACS雙向三端晶閘管

ACS Triac 或 ACST，可用作雙向開關(guān)三極管（Triac），且提高了電壓瞬變箍制和吸收能力。 這種器件和系統(tǒng)可成功地吸收負(fù)載交換以及電源線路產(chǎn)生的瞬變電壓，如IEC 61000-4-5所述。 ACST 箍制和過(guò)壓保護(hù)功能可保證系統(tǒng)和 ACST 安全的瞬間動(dòng)作。 從而簡(jiǎn)化電路，不需要 MOV 或緩沖器電路。 這些器件關(guān)斷電壓達(dá) 800 V，可選擇標(biāo)準(zhǔn)和邏輯電平門控。 器件采用 Fullpack、IPAK、DPAK、D2PAK 或 I2PAK 封裝。

ACS邏輯電平門

ACS are static-switch semiconductors for alternating current. They are simple-to-drive, sensitive-gate devices with highly inductive load switch-off capability. They are targeted at appliance actuators, such as water valves and drain pumps. Their logic-level gate characteristics allow direct input from the microcontroller. The high immunity of the device reduces the need for MOVs and snubbers in the circuit. These devices have a 600 V blocking capability with further clamping and crowbar features for large overvoltage transients. They are available in SO-8, SO-20, SOT-223 or TO-92 packages.
