**Vishay Intertech** · ESD And Surge Protection (TVS/ESD) · SMB(DO-214AA)

SM6T6V8A-E3 from Vishay Intertech, in a SMB(DO-214AA). 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, the end marked by the cathode band on uni-directional types such as SM6T6V8A (VWM 5.80 V, VBR 6.45 V to 7.14 V at 10 mA). |
| 2 | A | passive | Anode terminal, the unmarked end of the uni-directional SM6T6V8A, which is the end opposite the cathode band. |
