I am looking for a part or a suitable alternative to a C25M-02D. Looking at the data sheet it's a fast switching diode. I have had zero luck with finding this part or a suitable replacement. Can someone point me in the right direction please and thank you?

 

Look at:
Peak inverse voltage (replacement must be greater than or equal). MUCH greater will probably lead to higher voltage drop
Peak current (replacement must be greater than or equal). A little bit larger will probably lead to lower voltage drop
Reverse recovery time (replacement must be less than or equal). As small as you can find would be best.
