AD-BZX84C24 from Changjing, 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 | A | passive | Anode of the Zener diode; the equivalent circuit connects it to the diode symbol, which has a 24V nominal Zener voltage (22.8V to 25.6V at IZT = 5mA) for the AD-BZX84C24. |
| 2 | NC | unconnected | Not connected internally; pin 2 is drawn with no connection in the equivalent circuit. |
| 3 | K | passive | Cathode of the Zener diode; the equivalent circuit shows the diode bar side connected to pin 3, with maximum power dissipation of 300mW. |
