I am designing a switchable 75 ohm terminator circuit for a video
application using a Enhance Mode N-Channel MOSFET, ZVN4106F
(ZETEX) and a 75 ohm resistor. Please see the BMP attachment.
The Source is connected to ground. The Drain is connected to a
75ohm resistor and the other side of the 75ohm resistor end to
the video source-to-a video analyzer coax line.

Have you got room for a SIL reed relay?

eg, The Meder Electronic Micro SIL relay has a
footprint of about 15.2x3.9mm, about 2pF, coil to
contact, and takes less than 20mA from a 5v supply.
Switching speed is about 0.5mS. Their SIL05-xxx is
slightly larger, but takes only 10mA at 5V.
