On the transistor body, below nomenclature are words Dayton 77, implying it was possibly sold at hyphenation in. I have no specifications device, they likely available line. Sales in the USA only please. Motorola 2N6439 npn power transistor, unused. It is obviously unused, and might be a good candidate for your next project.
I have no way to test it so this is a scavenger hunt. Here is a nice Motorola vhf power transistor from an engineers estate.
