# S3GB-TP

**MCC Micro Commercial Components** · Diodes - General Purpose · DO-214AA(SMB)

S3GB-TP from MCC Micro Commercial Components, in a DO-214AA(SMB). 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 terminal at the end marked with the cathode band; the device passes 3.0A average forward current and blocks up to 400V DC (S3GB). |
| 2 | A | passive | Anode, the terminal opposite the cathode mark; forward voltage is 1.15V max at IFM=3.0A, TJ=25°C. |

## CAD (KiCad official)

- Symbol: `S3GB-TP`
- Footprint: `Diode_SMD:D_SMB`
- 3D model: DO-214AA(SMB) (KiCad packages3D, STEP)
- 3D model files: `s3gb-tp-etched.step` / `s3gb-tp-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `s3gb-tp.step` / `s3gb-tp.glb` are the bare package body.
