I have had VERY unreliable experience with the Silonex parts. I
used NSL-32SR3 which are meant to be the fast ones but I had
places where they would take several seconds to decay. Oddly, it
made a difference if I had them in an inline resistor verses as
one part of a voltage divider. Also, not necessarily a bad thing,
but their on resistance is much lower than in the
Vactec/PerkinElmer/Excilitas ones.
