Black diode, smaller than 1Nxxx, green band and green test: "R47". Glass diode with yellow band. No other markings. Thanks. I may have the answer, but No, I can't help you....but you can go through books and mfg semiconductor spec manuals....you can fish through IR's site too. I have a power supply myself that I need to boost to about 50 watts continuous, the coil can bolster it but I have to rebuild the network and upgrade a full bridge inhabited by dubious trolls..... hahaha. Maybe I'll just send away for a new dedicated unit made to specifications, the digits are unquestionable., the markings as diverse as makers......Good Luck! R. |
