# HS2D

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

HS2D from RUILON(Shenzhen Ruilongyuan Elec), in a 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 terminal, marked by the cathode line on the package; the datasheet gives VRRM of 200 V for HS2D and IF(AV) of 2.0 A. |
| 2 | A | passive | Anode terminal, the end opposite the cathode line; the datasheet gives IFSM of 50 A (60 Hz half-sine, 1 cycle) for the part. |

## CAD (KiCad official)

- Symbol: `HS2D`
- Footprint: `Diode_SMD:D_SMB`
- 3D model: SMB (KiCad packages3D, STEP)
- 3D model files: `hs2d-etched.step` / `hs2d-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `hs2d.step` / `hs2d.glb` are the bare package body.
