# MMSZ4697T1G

**onsemi** · Zener Diodes · SOD-123

MMSZ4697T1G from onsemi, in a SOD-123. 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 | Cathode | passive | Cathode terminal, indicated by the polarity band on the package; it is the Zener regulating terminal, and the datasheet gives no separate pin-level limits. |
| 2 | Anode | passive | Anode terminal, opposite the cathode polarity band; the datasheet gives no separate pin-level limits for this pin. |

## CAD (KiCad official)

- Symbol: `MMSZ4697T1G`
- Footprint: `Diode_SMD:D_SOD-123F`
- 3D model: SOD-123 (KiCad packages3D, STEP)
- 3D model files: `mmsz4697t1g-etched.step` / `mmsz4697t1g-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `mmsz4697t1g.step` / `mmsz4697t1g.glb` are the bare package body.
