# BZX84C5V6-RTK

**KEC Semicon** · Zener Diodes · SOT-23

BZX84C5V6-RTK from KEC Semicon, 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 | NC | unconnected | Pin 1 is labeled NC (no connection) in the SOT-23 pin list, so it is not assigned a function in this datasheet. |
| 2 | ANODE | passive | Pin 2 is the zener diode anode terminal; the datasheet gives no further electrical limit for this pin beyond the device ratings. |
| 3 | CATHODE | passive | Pin 3 is the zener diode cathode terminal; the datasheet gives no further electrical limit for this pin beyond the device ratings. |

## CAD (KiCad official)

- Symbol: `BZX84C5V6-RTK`
- Footprint: `Package_TO_SOT_SMD:SOT-23`
- 3D model: SOT-23 (KiCad packages3D, STEP)
- 3D model files: `bzx84c5v6-rtk-etched.step` / `bzx84c5v6-rtk-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `bzx84c5v6-rtk.step` / `bzx84c5v6-rtk.glb` are the bare package body.
