# MM1Z10B

**Shandong Jingdao Microelectronics** · Zener Diodes · SOD-123

MM1Z10B from Shandong Jingdao Microelectronics, 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 of the Zener diode; the datasheet gives no pin-specific limit, so it is bound by the absolute maximum ratings (Ptot 500 mW, Tj/Tstg -55 to +150 °C). |
| 2 | Anode | passive | Anode terminal of the Zener diode; the datasheet gives no pin-specific limit, so it is bound by the absolute maximum ratings (Ptot 500 mW, Tj/Tstg -55 to +150 °C). |

## Key specifications

| Parameter | Value |

## CAD (KiCad official)

- Symbol: `MM1Z10B`
- Footprint: `Diode_SMD:D_SOD-123F`
- 3D model: SOD-123 (KiCad packages3D, STEP)
- 3D model files: `mm1z10b-etched.step` / `mm1z10b-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `mm1z10b.step` / `mm1z10b.glb` are the bare package body.
