AD-BZX84C8V2
Changjing · Zener Diodes · SOT-23
AD-BZX84C8V2 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 (equivalent circuit, page 1); the 8.2V part (Z7 marking) has VZ 7.7-8.7V at IZT = 5mA. |
| 2 | NC | unconnected | No internal connection shown in the equivalent circuit; pin 2 is drawn without any link to the diode. |
| 3 | K | passive | Cathode of the Zener diode (equivalent circuit, page 1); power dissipation is rated at 300mW. |
