Datasheet for the RQ3E070BN, a ROHM N-channel power MOSFET, supplied as a fairly large 2.59 MB PDF. Transistors of this class appear in DC-DC converters and load switching circuits on laptop and other device motherboards. The document details the pinout, drain-source voltage, on-resistance, gate threshold and package dimensions. Use it to identify the gate, drain and source connections, measure for shorts in the converter stage and confirm that any replacement has comparable ratings and an identical footprint.
