Question Is this MOSFET transistor?

I got few experiance on differentiate PNP and NPN transistors, but I got a transistor that doesn't same with other transistors that I bought, I got no idea that is PNP or NPN transistor, I was suspected it was a MOSFEET, but I really don't have any idea how to differentiate MOSFET TR, anyone know how?

Those part numbers sound like standard voltage regs to me.

Second that. They seem to be standard voltage regulators...
Those who say it can't be done should not stop those who are doing it.
