The Optoelectronics Group of Vishay Semiconductor is the little kid on the block when it comes to Vishay products. Most know Vishay for resistors, capacitors, diodes, or MOSFETs. So the Opto Group had to do something different to get your attention. As the tag line says, we have a lot of stellar products and this is our way of telling you about them first. It is also your way of connecting directly with us and telling us what you think. We should both have some fun doing it.
