Hi,
I am looking for a FET with following specs.
- Vgs = 1.2 VOLTS (max)
- Vds = between 20 to 30volts
- Id = 60mA
Please advice John

My advise is to make your question clear.
If it's a MOSFET or a JFET, say "I'm trying to figure out if this data sheet is for a MOSFET or a JFET".
If you had, I would say probably not, because they're letting you have a positive Vgs, which would forward bias the gate in a JFET.

Do you need to implement control loops in software?
"Applied Control Theory for Embedded Systems" gives you just what it says.

Indeed. Perhaps he wants a small low-gate-voltage MOSFET, like a Supertex TN0104N3 (in a TO-92 pkg) or TN0604, or ... Mouser stocks them.
IIRC I saw a logic level mosfet with Vgs spec'd as low as 0.85V. (Neglecting that freaky chip with Vgs=0) I can't recall the Id @ Vgs 0.85V. And I can't recall the part number..but I saw it a few days ago on Digikey.

** You need a " lateral " MOSFET to do that:Eg:
