3-pin MOSFET that can pass 150 mA

[Tomás Ó hÉilidhe]

I'm looking for a 3-pin MOSFET transistor that can pass 150 mA. It
doesn't matter whether it's NMOS or PMOS, either will do the trick.

Is there any sort of "bread and butter" device that everyone uses?
I'll be using a microcontroller pin to turn the transistor off and on,
and when it's on it will be providing a path directly to ground (hence
I don't need a 4-pin device).

The microcontroller pin is 5 V for high and 0 V for low.

Bet it's not.

When you're designing, NEVER rely on "typical" or "nominal" values.
Only depend on the guaranteed minimum logic high and the guaranteed
maximum logic lows (at specified Vcc and source/sink currents).
Otherwise you'll find yourself scratching your head wondering why
something isn't working reliably (or at all).

Once you get a number, where do you plan to BUY it?
Why don't you go directly to that vendor
and do a parametric search to see what they have?

This side of the pond,
DigiKey's search engine is quite good for finding things.
You can compare prices and see if it is in stock.
