P6SMB18CA-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 | A1 | passive | Terminal 1 of the bidirectional P6SMB18CA TVS (VWM 15.3 V, VBR 17.1 to 18.9 V at 1.0 mA, VC 25.2 V at 23.8 A); electrical characteristics apply in both directions and there is no polarity marking. |
| 2 | A2 | passive | Terminal 2 of the bidirectional P6SMB18CA TVS (600 W peak pulse power at 10/1000 μs); interchangeable with terminal 1 since bidirectional types have no cathode band. |
