Sadly, Google searches require the entire word to work.
Could it be Motorola's mmdf7n02z, a dual 20V 7A NMOS SO-8,
introduced in 1997, and discontinued by ON Semi in 2003?
This was one of their "EZFET" parts, with a monolithic
back−to−back gate-ro-source zener diode. They suggested
Fairchild's fds9926A as a replacement. It's similar and
has the same pinout, but no gate zeners. But its Rds(on)
of 43 milliohms max with Vgs = 2.5V is pretty attractive.
