The Nexperia PMCM6501VNE/S500Z is a 12V N-channel MOSFET. The '12V, N-CH' descriptor tells you this is a low-voltage, single-channel discrete switch — the kind you'd use for load switching, DC-DC converter low-side, or power-rail gating in a 5V or 3.3V system where the gate drive is comfortably below 12V.
That means Nexperia is still manufacturing it, no last-time-buy notice has been issued, and it remains listed in the current product portfolio.
