# S3BC

**Shandong Jingdao Microelectronics** · Diodes - General Purpose · SMC(DO-214AB)

S3BC from Shandong Jingdao Microelectronics, 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 of the rectifier; for the S3BC variant the maximum repetitive peak reverse voltage is 100 V, with 3 A maximum average forward rectified current. |
| 2 | Anode | passive | Anode terminal of the rectifier, opposite polarity to the cathode; the device is rated for a maximum average forward rectified current of 3 A and a maximum instantaneous forward voltage of 1.0 V at 3 A. |

## CAD (KiCad official)

- Symbol: `S3BC`
- Footprint: `Diode_SMD:D_SMC`
- 3D model: SMC(DO-214AB) (KiCad packages3D, STEP)
- 3D model files: `s3bc-etched.step` / `s3bc-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `s3bc.step` / `s3bc.glb` are the bare package body.
