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

S3J-AU from PANJIT International, 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 | Cathode | passive | Cathode terminal, identified by the color band on the package; the S3J-AU is rated for a maximum recurrent peak reverse voltage of 600 V and a DC blocking voltage of 600 V. |
| 2 | Anode | passive | Anode terminal; the maximum forward voltage is 1.2 V at 3 A, and the maximum average forward rectified current is 3 A at TL = 75 °C. |

## CAD (KiCad official)

- Symbol: `S3J-AU`
- Footprint: `Diode_SMD:D_SMC`
- 3D model: SMC(DO-214AB) (KiCad packages3D, STEP)
- 3D model files: `s3j-au-etched.step` / `s3j-au-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `s3j-au.step` / `s3j-au.glb` are the bare package body.
