# HS3G

**RUILON(Shenzhen Ruilongyuan Elec)** · High Effic Rectifier · SMC

HS3G from RUILON(Shenzhen Ruilongyuan Elec), in a SMC. 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, marked by the cathode line on the package; HS3G is rated for 400 V repetitive peak reverse voltage and 3 A average forward current. |
| 2 | A | passive | Anode terminal of the rectifier diode; peak forward voltage is 1.3 V at IFM=3.0A for the HS3G and reverse recovery time is 50 ns. |

## CAD (KiCad official)

- Symbol: `HS3G`
- Footprint: `Diode_SMD:D_SMC`
- 3D model: SMC (KiCad packages3D, STEP)
- 3D model files: `hs3g-etched.step` / `hs3g-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `hs3g.step` / `hs3g.glb` are the bare package body.
