# AD-BZX84C36

**Changjing** · Zener Diodes · SOT-23

AD-BZX84C36 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 | Zener diode anode, the lower-left terminal in the equivalent circuit (polarity read from the drawing, not stated in text). |
| 2 | NC | unconnected | No internal connection to the diode shown in the equivalent circuit. |
| 3 | K | passive | Zener diode cathode, the top terminal in the equivalent circuit; AD-BZX84C36 has VZ of 34.0 to 38.0 V at IZT = 2 mA (polarity read from the drawing, not stated in text). |
