We see from your search that you're looking for information on the term "Optocoupler",
and we have a large number of manufacturers' news releases and technical articles here on Electronicstalk which will be of interest.
Let me be your guide.
Start with
the news release Digital optocouplers have industrial specs from
Avago Technologies, which we summarised at the time by saying "Wide temperature optocouplers are extremely reliable and ideal for use in applications that operate in harsh industrial environments".
A few weeks before,
we featured the news release Optocoupler protects in hybrid vehicles from
Avago Technologies: "Intelligent power module digital interface optocoupler offers high reliability, high performance, ease of integration and superior heat dissipation".
In November 2007, we covered the news from Avago Technologies
concerning its ACPL-H312
- take a look at Small advantages for SO-8 packaged optocoupler
which says: "Device addresses isolation needs where space and efficiency are a premium, such as motor drives, industrial inverters, air conditioners, washing machines and switching power supplies".
Take a look also at the news release from Everlight Electronics, Optocouplers provide design flexibility,
as well as Display distribution deal expanded from Farnell,
and High-speed IGBT optocouplers are easy to use from Avago Technologies.
