Hello Everyone I have a what looks like a diode in a TO220 package but only two pins it has the motorola logo and the following marking top line 98 08 some have 98 11 so I think this is the production code next line U805 maybe a inhouse number followed by motorola logo and KA any idea what it is as I have a few of these
Thanks
it has
MUR805
Is the mounting tab isolated or metal? Was it fixed to a PCB with the tab or vertical?

They have high current, low(ish) forward voltage, and they're fast, so one use might be for general protection of DC circuits against reverse polarity, especially those that might be destroyed before a fuse can blow. Connect them across the supply terminals, reverse biased, just after the input fuse. This will make sure the only casualty of reverse connection is that fuse. Especially useful for stuff plugged to car batteries. They're meant for better things, but if you already have them...
Someone might come up with a more sensible answer soon.
