What this Zener TVS protects and where it mounts
onsemi lists the P6SMB16AT3 as Obsolete.
AEC-Q101 and the 600W clamping envelope
The 600W peak pulse rating at 10/1000 µs is the energy it can absorb in a single surge; the 1110 pF capacitance at 1 MHz is high enough that it will load a high-speed data line, so it is best suited for power-rail clamping rather than signal-line protection.
