BZX84C7V5LT1G 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 anode terminal; the datasheet gives the pinout as 1-Anode, 2-No Connection, 3-Cathode for this SOT-23 device. |
| 2 | NC | unconnected | No connection; the datasheet specifies this pin as having no internal connection. |
| 3 | CATHODE | passive | Zener cathode terminal, identified on the package by the polarity band. |
