[Amps] Info needed

[Dan Hearn]

I recently acquired several HV rectifier units from an estate sale. A Google
search did not give me information on them. Any help in determining their
voltage and current ratings will be appreciated.
1. Unitrode UDA5. It looks like and has the same dimensions as a UDE5 on the
Surplus Sales Nebraska site.
2. Varo VC80X
3. Semtec SDHD 15K. Also SDHD 5K
4. Solitron C711 7410
5. IRC 6809
Tnx, Dan, N5AR
