FDA217 spice model

Carlos Delfino All Messages By This Member #153752 Hi,? I started studying a project using 4n25 to control a mosfet, but I was suggested to use the fda217, does anyone have a model of it that they can share? regards -- Carlos Delfino

Carlos Delfino All Messages By This Member #153754 Yes, yes, I'm using it, but as I need to control a MOSFET, they suggested I switch to this other optocoupler as it would better solve the problem I'm facing. -- Carlos Delfino Em seg., 20 de mai. de 2024 às 00:29, Andy I via <AI.egrps+io=[email protected]> escreveu: toggle quoted message Show quoted text I don't know if this helps, but are you aware that LTspice comes equipped with a 4n25 model?

Some model files even include the .asy file, All you need is to take the time and effort to search their web site. Mike
Tom All Messages By This Member #153758 4n25 is an opto or photo coupler. LED irradiating a light sensitive NPN transistor fda217 is a photo voltaic isolator. LED irradiating an series array of photo voltaic cells? They are two different types of components. They are used in a circuit differently
Carlos Delfino All Messages By This Member #153764 I found references for the?VOM1271, the other two I didn't find anything for now. From what I could see,?VOM1271?is very similar to FDA217, but?better documented. -- Carlos Delfino Quem sou:? Keybase (PGP): ORCID:?

Mike Fraser All Messages By This Member #153774 All, The VISHAY VOMDA1271 device simulates correctly. The VISHAY LH1262 device fails due to a defective spice model. The VISHAY VO1263 device fails due to a defective spice model. I have submitted all of my simulation files to VISHAY and requested that they correct their spice files. I will post a reply when I receive a response from VISHAY. Mike
