# BZX84-C11

**Nexperia** · Zener Diodes · SOT-23(TO-236AB)

BZX84-C11 from Nexperia, in a SOT-23(TO-236AB). 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 voltage regulator diode; the datasheet gives no separate electrical limit for this pin. |
| 2 | n.c. | unconnected | Not connected; the datasheet specifies no electrical function for this pin. |
| 3 | K | passive | Cathode of the voltage regulator diode; the datasheet gives no separate electrical limit for this pin. |

## CAD (KiCad official)

- Symbol: `BZX84-C11`
- Footprint: `Package_TO_SOT_SMD:SOT-23`
- 3D model: SOT-23(TO-236AB) (KiCad packages3D, STEP)
- 3D model files: `bzx84-c11-etched.step` / `bzx84-c11-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `bzx84-c11.step` / `bzx84-c11.glb` are the bare package body.
