BZX84C2V4LT1G

onsemi · Zener Diodes · SOT-23

BZX84C2V4LT1G 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 Zener diode anode, shown as pin 1 in the SOT-23 Style 8 outline and the Electrical Characteristics pinout (1-Anode, 2-No Connection, 3-Cathode).
2 NC unconnected No connection, as stated in the datasheet pinout (2-No Connection) and the Style 8 outline.
3 CATHODE passive Zener diode cathode, identified by the polarity band on the package, per the datasheet pinout (3-Cathode).
