BZX84B8V2LT1G from onsemi, in a SOT-23. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin	Name	Type	Function
1	ANODE	passive	Anode of the Zener diode; the datasheet's SOT-23 Style 8 pinout and the electrical characteristics pinout line both assign the anode to pin 1.
2	NO CONNECTION	unconnected	Pin 2 is marked No Connection in the SOT-23 Style 8 outline and in the electrical characteristics pinout note, so it is not connected internally.
3	CATHODE	passive	Cathode of the Zener diode, identified on the package by the polarity band per the mechanical characteristics.
