Did you read the data sheet AT ALL?. The BSS138... Data sheet enclosed. Btw did you read what the OP wanted to do with the FET?... Something about a 150 Ma Light???
That link is to a MOSFET that is nothing like the RFP30N06LE - it has a max drain current of 0.2A rather than 30A, an on resistance of 1.4ohms not 0.047 ohms, it requires 10V of gate drive to turn on properly (not 4.5V).
Not quite it is a LOGIC LEVEL MOSFET...
The OP wasn't looking for a 30A SOT23 package... just a little bitty Mosfet for a pilot light...
I'm wanting to make a SMD version of this. I need to turn a 12 volt light on/off that draws about 150 mA.
(OP's FIRST POST... it's the caption... Under that BIG picture of the Mosfet.
This device would WORK PERFECTLY FROM A 3V3 Logic output... The first requirement for an "Expert..." is the ability to read a data sheet... Before you quote a worthless opinion. IMHSHO
