# DSR1M

**FUXINSEMI** · Diodes - General Purpose · SOD-123

DSR1M from FUXINSEMI, in a SOD-123. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | K | passive | Cathode of the rectifier diode. Marked by the color band on the package. Rated VRRM = 1000V, IR = 5.0µA @ TA=25°C at rated DC blocking voltage. |
| 2 | A | passive | Anode of the rectifier diode. Average forward current I(AV) = 1.0A at TL = 110°C; VF = 1.1V max at 1.0A; IFSM = 25A peak (8.3ms single half sine). |

## Ordering variants

Same part, different packaging or reel option.

- `DSR1M`

## CAD (KiCad official)

- Symbol: `DSR1M`
- Footprint: `Diode_SMD:D_SOD-123`
- 3D model: SOD-123 (KiCad packages3D, STEP)
- 3D model files: `dsr1m-etched.step` / `dsr1m-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `dsr1m.step` / `dsr1m.glb` are the bare package body.
