# SZF1110A

**ZHIDE** · Zener Diodes · SOD-123FL

SZF1110A from ZHIDE, in a SOD-123FL. 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 | K | passive | Cathode, the end marked with the color band; it goes positive relative to the anode in Zener breakdown (VZ 110 V nominal, 104.50 to 115.50 V for SZF1110A). |
| 2 | A | passive | Anode, the end without the color band; the forward voltage is at most 1.2 V at IF = 200 mA. |

## CAD (KiCad official)

- Symbol: `SZF1110A`
- Footprint: `Diode_SMD:D_SOD-123F`
- 3D model: SOD-123FL (KiCad packages3D, STEP)
- 3D model files: `szf1110a-etched.step` / `szf1110a-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `szf1110a.step` / `szf1110a.glb` are the bare package body.
