# MSK340A

**Shikues** · Schottky Barrier Diodes (SBD) · SMA

MSK340A from Shikues, 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 of the Schottky diode; the device blocks up to VRRM 45 V min (50 V typ) at 0.5 mA and carries IF(AV) of 5 A. |
| 2 | Anode | passive | Anode of the Schottky diode; forward voltage drop is 0.30 V at 1 A, 0.35 V at 3 A and 0.42 V typ (0.46 V max) at 5 A. |

## CAD (KiCad official)

- Symbol: `MSK340A`
- Footprint: `Diode_SMD:D_SMA`
- 3D model: SMA (KiCad packages3D, STEP)
- 3D model files: `msk340a-etched.step` / `msk340a-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `msk340a.step` / `msk340a.glb` are the bare package body.
