I believe the R2M is an avalanche diode which will short if the supply
line goes above 130V.
I would only use the original diode for this. You should be able to get
those at your favorite supplier. my supplier in Toronto has them listed
for $1.00 CDN in their authorized dealer section. I probably have some
in stock too if you want to email me about it.
