This one should work for you. http://ca.mouser.com/ProductDetail/N...EnSri0l7uMU%3d . I've not run into a MTZ series before but the sheet looks like this one will work. Don't know where you would get one from.

it's just a 500mw 30v zener diode,
any zener that's 30v and atleast 500mw will do.
i'd fit a 1.3w because i like to go up with the ratings.
