Does anyone here know what the component labeled "G337 V2" on the Antminer S5 hashboards is? It's a 2-pin package, looks to be built for high current, and is silkscreen labeled C2, C3, etc. There's one in between each pair of ASICs -- i.e., one for each stage in the string, shared by both strings. My best guess is that they are shunt voltage regulators intended to serve as a bypass in case the voltage gets too high (dead ASIC?), but I don't really know. Ideally, if someone at Bitmain could chime in with a link to a datasheet or a part number, that would be ideal. We're investigating an issue on behalf of another miner in which some of them appear to have burned out.
