P-channel MOSFET — what the polarity means for your BOM
The 2SJ495-S12-AZ is a P-channel power MOSFET, typically specified in high-side load switching, battery protection, and reverse-polarity protection circuits where the load is grounded and the supply rail is switched. P-channel devices simplify drive circuitry by allowing the source to connect to the supply rail and the drain to the load, eliminating the need for a charge pump above the rail voltage.
ROHS3 compliance is confirmed, covering the EU RoHS restricted-substance list including the four phthalates added under Directive 2015/863.
Bulk packaging — procurement planning factor
This part is, not on tape-and-reel or in trays. For high-volume pick-and-place assembly, confirm with your contract manufacturer whether Bulk tubes or loose parts are accepted, or if a tape-and-reel conversion service is needed.
