Motorola zener diode

[James260265]

got a diode in a fried Iskra CDI from an old hirth engine, marked up, Mk (Motorola logo) 79 c4v9 415
has anyone got any clues as to an equivalent?

pretty sure the 79 c4v9 is the material type but 415?

Looks like a 4.9 V zener, not a vey common value. Could you upload cleat pictures of the diode (< 300kB/picture)?

Pictures taken to show all markings on circumference. Mk (Motorola logo) 79 c4v9 415

I read this as C4V7, not V9, a much more plausible value: 4.7 V, 0.5 W. Datasheet is here.

you are correct D'oh! So what exactly am I looking for? There are so many variants of the 4.7v, 0.5w zener diodes

I linked the datasheet in post #5.
