Mysetery Diode?!?!

Help! I've just sorted through my parts collection, and i've come across these diodes in a bag, and i have no idea what they are, i must have bought them for a project at somepoint in time..

so they are clear, but red, w/ black stripe and the only marking on the says 'C11PH', i have googled, but to no avail..

I bought some 9.1 zeners for a build which never happened a while ago, and now i need some, some i'm hoping they are those, but i doubt it!

hopefully someone knows!
