    Can anyone help identify this SOT-23 MOSFET? Pretty sure it's N-Channel, and the circuit is supposed to turn on with 3.3V. It's switching ground for a high power LED, but the MOSFET is shorted out and I need to replace it. Can't find any cross-reference on the markings 2AA3B.

    Google for "SMD device codes" and "2A", OR "3B".

    One of those is the device code.
