Last week we received a lot of 7805 voltage regulators in TO-220 package
and I think they are fake.

They are marked as On Semiconductor parts, but the metal tab is too
thin, about the same thickness as the package pins. I can bend it with
my hands.
In every TO-220 package I have ever seen before, the metal tab is much
thicker than the pins.
