Hi,

I am looking for a FET with following specs.

1. Vgs = 1.2 VOLTS (max)
2. Vds = between 20 to 30volts
3. 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.
