**Slkor(SLKORMICRO Elec.)** · TVS · SMB

P6SMB27A from Slkor(SLKORMICRO Elec.), 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, marked by the color band on the unidirectional P6SMB27A (VWM 23.1 V, V(BR) 25.7-28.4 V at 1.0 mA, VC 37.5 V at 16.8 A Ippm). |
| 2 | A | passive | Anode of the unidirectional P6SMB27A TVS diode, the end opposite the cathode color band; maximum transient forward voltage 3.5 V at 50 A. |

## CAD (KiCad official)

- Symbol: `P6SMB27A`
- Footprint: `Diode_SMD:D_SMB`
- 3D model: SMB (KiCad packages3D, STEP)
- 3D model files: `p6smb27a-etched.step` / `p6smb27a-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `p6smb27a.step` / `p6smb27a.glb` are the bare package body.
