| "Simistor"? |

In another forum, somebody referred to an ST-made component, ACST6, as a "simistor", a term I had never heard of before. I don't feel totally ignorant though, as I note that even ST do not seem to use that name, preferring the long-winded "Overvoltage protected AC switch" - https://www.st.com/resource/en/datasheet/acst6.pdf. An old thread here hints that "simistor" could be derived from "symmetric thyristor", and by observation, Google seems to treat "simistor" as some sort of synonym of "triac", but such usage seems to be pretty rare. I also found that the term has been used for a completely different component, the "silicon thermistor" - https://www.theengineer.co.uk/silicon-thermistor/. So, if somebody were to mention "simistor" to you, would you know what they were talking about? |

I've never heard of it. The data sheet is for a snubberless TRIAC. I presume it's a marketing term. |

It's a triac. Triacs are called simistor in Russian. https://ru.wikipedia.org/wiki/%D0%A1%D0%B8%D0%BC%D0%B8%D1%81%D1%82%D0%BE%D1%80 |

When I went to school, the exact wording for triacs was "simistor" or the long version was exactly "symmetric thyristor". I guess maybe coming from Russian - https://www.google.com/search?sxsrf=ALeKk03_nn1c7UZULvVcKPkEnjoFOcwy4w%3A1610912449941&source=hp&ei=wZIEYLC1N_TTgwfxx7XQDA&q=%D1%81%D0%B8%D0%BC%D0%B8%D1%81%D1%82%D0%BE%D1%80&oq=%D1%81%D0%B8%D0%BC%D0%B8%D1%81%D1%82%D0%BE%D1%80&gs_lcp=CgZwc3ktYWIQAzIFCAAQyQMyBAgAEB4yBAgAEB4yBAgAEB4yBAgAEB4yBAgAEB4yBAgAEB4yBAgAEB4yBAgAEB4yBAgAEB46CwgAELEDEIMBEMkDOggIABCxAxCDAToICC4QsQMQgwE6AgguOgUIABCxAzoICAAQsQMQyQM6AggAOggILhDJAxCTAlDqCFjhD2CEEWgAcAB4AIABcIgB3gWSAQM2LjKYAQCgAQGqAQdnd3Mtd2l6&sclient=psy-ab&ved=0ahUKEwjwmd3C3KPuAhX06eAKHfFjDcoQ4dUDCAk&uact=5 |

It was not obvious that ST had used it as a marketing term, but maybe I missed that. --- Quote from: wraper on January 17, 2021, 07:40:12 pm ---It's a triac.
