# 3DSR1M

**JUXING** · Diodes - General Purpose · SOD-323

3DSR1M from JUXING, in a SOD-323. 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 glass-passivated standard rectifier; the 3DSR1A THRU 3DSR1M series is rated 1.0 A forward current with reverse voltage up to 1000 V. |
| 2 | Anode | passive | Anode terminal of the glass-passivated standard rectifier, forming the forward-current path opposite the cathode in the 1.0 A SOD-323 surface-mount device. |

## CAD (KiCad official)

- Symbol: `3DSR1M`
- Footprint: `Diode_SMD:D_SOD-323`
- 3D model: SOD-323 (KiCad packages3D, STEP)
- 3D model files: `3dsr1m-etched.step` / `3dsr1m-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `3dsr1m.step` / `3dsr1m.glb` are the bare package body.
