Diode replacement

Hi
I'm trying to repair a PCB board for an old treadmill... The diode pictured below seems to be faulty as I'm getting no resistance either way. Only trouble is the only replacement I can find is on Alibaba from China. Does anyone know if there's a similar one that would work?
Thanks Mike

From the info I can find it's rated at 30A, 600V

Something like this should be suitable?

Brilliant thanks
