BZX84B24LT1G 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 terminal of the Zener diode; the cathode is identified by the polarity band on the package. |
| 2 | NO CONNECTION | unconnected | No internal connection; this pin is not connected to the device. |
| 3 | CATHODE | passive | Cathode terminal of the Zener diode, marked by the polarity band on the package. |
