# S2MA

**FUXINSEMI** · Diodes - General Purpose · SMA(DO-214AC)

S2MA from FUXINSEMI, in a SMA(DO-214AC). 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, marked by the color band on the package; the datasheet's polarity note says the color band denotes the cathode end. |
| 2 | anode | passive | Anode terminal; the S2MA is a 1000 V repetitive peak reverse voltage, 2.0 A general purpose rectifier, so this pin is the anode side of the diode. |

## CAD (KiCad official)

- Symbol: `S2MA`
- Footprint: `Diode_SMD:D_SMA`
- 3D model: SMA(DO-214AC) (KiCad packages3D, STEP)
- 3D model files: `s2ma-etched.step` / `s2ma-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `s2ma.step` / `s2ma.glb` are the bare package body.
