# MMBZ5V6A

**Shikues** · ESD And Surge Protection (TVS/ESD) · SOT-23

MMBZ5V6A from Shikues, 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 | K1 | passive | Cathode of the first Zener TVS diode (unidirectional use: circuit tied to pins 1 and 3), 3.0 V VRWM, 5.32-5.88 V breakdown at 20 mA. |
| 2 | K2 | passive | Cathode of the second Zener TVS diode (unidirectional use: circuit tied to pins 2 and 3), 3.0 V VRWM, 5.32-5.88 V breakdown at 20 mA. |
| 3 | A | passive | Common anode of both Zener TVS diodes, shared by pins 1 and 2. |

## CAD (KiCad official)

- Symbol: `MMBZ5V6A`
- Footprint: `Package_TO_SOT_SMD:SOT-23`
- 3D model: SOT-23 (KiCad packages3D, STEP)
- 3D model files: `mmbz5v6a-etched.step` / `mmbz5v6a-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `mmbz5v6a.step` / `mmbz5v6a.glb` are the bare package body.
