# S3MSMC

**BORN** · Diodes - General Purpose · SMC(DO-214AB)

S3MSMC from BORN, in a SMC(DO-214AB). 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 terminal, marked by the color band on the molded body; the S3M version blocks up to 1000 V DC (VRRM 1000 V). |
| 2 | A | passive | Anode terminal at the end opposite the color band; rated for 3.0 A average forward current at TL=75 C and 100 A peak surge (8.3 ms). |

## CAD (KiCad official)

- Symbol: `S3MSMC`
- Footprint: `Diode_SMD:D_SMC`
- 3D model: SMC(DO-214AB) (KiCad packages3D, STEP)
- 3D model files: `s3msmc-etched.step` / `s3msmc-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `s3msmc.step` / `s3msmc.glb` are the bare package body.
