voltage transient suppression circuits

[fireplus]

Dear All,

i'm designing a speed sensor interface circuit i need to protect my circuit form over voltage transient without effecting on the sensor signal , i here a bout VTS but i didn't find a lot of information about them (signal sensor can be from 0.5v pp to 50v pp (ac or dc))
so if any body can help me in design the interface circuit and it's protection circuits

Yours,

Try protection devices from SGS - Thomson www.st.com, Semtech www.semtech.com and Teccor-Littelfuse www.teccor.com. By searching these sites you can decide which protection scheme is best suited for your application. An important point is the energy that you expect to find in your transients.
