Complementary pair in one 8-SOIC — what it saves you
The IRF7319TRPBF from the HEXFET series packs an N-channel and a P-channel MOSFET into a single 8-SOIC package. That complementary pair saves you a second part number on the BOM and cuts board area in half-bridge, push-pull, or synchronous-rectifier stages where you need both polarities. That Rds(on) figure is the one to size your conduction losses against — at 5.8 A continuous, expect about 0.97 W dissipation per channel before the 2 W package limit becomes the constraint.
It will hold its ratings in avionics, satellite, or downhole tool environments where the board sees wide thermal swings. The 8-SOIC copper pad area under the die sets the thermal resistance — keep the PCB copper pour generous to stay below the 150°C limit at full load. Gate charge is 33 nC at 10 V, and input capacitance is 650 pF at 25 V drain-source.
Lifecycle and sourcing — no LTB worry here
No last-time-buy deadline to track, no scramble for surplus stock. ROHS3 compliant per the listing, so it clears the current EU restriction directive without an exemption.
