Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me.

Hi Everyone, I want to know if you think these diodes would be any good (Schottky SR5100) compared to (R-6 1000V 1000Voltage 6A) datasheet and Ebay Find. Ebay Link to 5100 Diode PDF Datasheet Cheers, Shaun EDIT: Sorry, My array is no more then 3x 22v panels.. (66v-80v) @ 3.5A (44 cells @0.5v (22v) |

Hi Shaun How are you going to use the diodes, as blocking diodes in the array, or elsewhere? Schottky diodes are fast switching, so work well in switchmode power supplies, etc. For a solar array, a regualr diode will work, but it depends on hows its wired, across the cell or in series.

it will not be required in series because my controllers have built in diodes, perhaps I will, But I plan to use for shade protection / hotspot protection basicly 1 Diode in parallel with POS/NEG for each diode so you think the normal 6A 1000v diode is best, I think I will go that route, as it noticed I wouldnt save too much voltage for the schottky cheers, |

Hi Shaun The 1000volt rating is a bit overkill, since it will only see a few volts, but if you can get them cheap enough then go for it. The high voltage diodes are usually a bit more robust anyay. Glenn The best time to plant a tree was twenty years ago, the second best time is right now. JAQ |
