# SK34

**MSKSEMI** · Diodes - General Purpose · SMA

SK34 from MSKSEMI, 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 | K | passive | Cathode, the end marked by the color band; the schematic shows the diode conducting toward this terminal, rated for 40 V maximum DC blocking voltage (SK34). |
| 2 | A | passive | Anode, the terminal opposite the color band; carries up to 3.0 A maximum average forward rectified current. |

## CAD (KiCad official)

- Symbol: `SK34`
- Footprint: `Diode_SMD:D_SMA`
- 3D model: SMA (KiCad packages3D, STEP)
- 3D model files: `sk34-etched.step` / `sk34-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `sk34.step` / `sk34.glb` are the bare package body.
