# MM3Z7V5C

**onsemi** · Zener Diodes · SOD-323FL

MM3Z7V5C from onsemi, in a SOD-323FL. 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 | ANODE | passive | Anode terminal of the Zener diode; the connection diagram identifies pin 1 as ANODE, and the device must stay within the absolute maximum ratings (PD 200 mW, IZM = PD/VZ). |
| 2 | CATHODE | passive | Cathode terminal of the Zener diode, marked by the band on the package (band denotes cathode); the connection diagram identifies pin 2 as CATHODE. |

## CAD (KiCad official)

- Symbol: `MM3Z7V5C`
- Footprint: `Diode_SMD:D_SOD-323F`
- 3D model: SOD-323FL (KiCad packages3D, STEP)
- 3D model files: `mm3z7v5c-etched.step` / `mm3z7v5c-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `mm3z7v5c.step` / `mm3z7v5c.glb` are the bare package body.
