# US1G_R1_00101

**PANJIT International** · Fast Recovery / High Efficiency Diodes · SMA

US1G_R1_00101 from PANJIT International, in a SMA. 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, identified by the color band on the package, since the datasheet states the color band denotes the cathode end. |
| 2 | Anode | passive | Anode terminal, the opposite terminal to the cathode, of this ultrafast surface-mount rectifier rated 1 A average forward current. |

## CAD (KiCad official)

- Symbol: `US1G_R1_00101`
- Footprint: `Diode_SMD:D_SMA`
- 3D model: SMA (KiCad packages3D, STEP)
- 3D model files: `us1g-r1-00101-etched.step` / `us1g-r1-00101-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `us1g-r1-00101.step` / `us1g-r1-00101.glb` are the bare package body.
