# MUR160SB

**amsem** · Fast Recovery/High Efficiency Diode · SMB

MUR160SB from amsem, 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 color band on the package; the datasheet states 'Color band denotes cathode end'. |
| 2 | A | passive | Anode terminal, the end opposite the color band; rated for 1.0 A average forward current and 600 V repetitive peak reverse voltage. |

## CAD (KiCad official)

- Symbol: `MUR160SB`
- Footprint: `Diode_SMD:D_SMB`
- 3D model: SMB (KiCad packages3D, STEP)
- 3D model files: `mur160sb-etched.step` / `mur160sb-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `mur160sb.step` / `mur160sb.glb` are the bare package body.
