I need some help in identifying optocoupler technology. Some time ago i stumbled across an opto device whihc consists of LED source and a photo cell ( of the solar panel variety ) which can be used to: a) provide isolation for the signal b) provide low level power to the isolated circuit I cant recall where or what the device is, I ask for any pointers to the device. |

This was fast... dangerously fast...Thank You Yes this is the kind of device I was looking for. |

These were my favourite part - https://www.silabs.com/documents/public/data-sheets/Si844x.pdf damn fast / logic Not for new designs? Need to check if there is a replacement. |

What I want to know is why we don't see ever increasingly smaller optocouplers in SMT packages. I don't remember now why I was looking; but I wanted something really small to work in an SMT design... sadly; I couldn't find anything really smaller than SO8. :( I was kind of hoping for some SC7 or hell even BGA style for the really small boards. I actually toyed with the idea of combining a photo transistor and smd right angle diode. |

What coincidence , just used a VOM1271T + 2 beefy high voltage N mosfets to build a DIY SSR, really handy. :-+ |
