https://ssdi-power.com/news/sff75p10s2 - When used in load switching applications, N-channel MOSFETs require additional circuitry to produce the gate voltage needed to turn on the device. By selecting a P-channel MOSFET instead of an N-channel device, design engineers can simplify the circuit design and optimize board space. The SFF75P10S2 PFET also offers higher current and lower RDSon compared to the 2N7425U and 2N7550U2. Contact SSDI for more HiRel product solutions.
