# CMS01

**TOSHIBA** · Schottky Diodes · SOD-128

CMS01 from TOSHIBA, in a SOD-128. 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 | A | passive | Anode (marked 1 on the package drawing); forward current up to IF(AV) = 3.0 A flows from anode to cathode, with VFM = 0.37 V max at 3.0 A. |
| 2 | K | passive | Cathode (marked 2 on the package drawing); repetitive peak reverse voltage VRRM = 30 V. |

## CAD (KiCad official)

- Symbol: `CMS01`
- Footprint: `Diode_SMD:D_SOD-128`
- 3D model: SOD-128 (KiCad packages3D, STEP)
- 3D model files: `cms01-etched.step` / `cms01-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `cms01.step` / `cms01.glb` are the bare package body.
