P6SMB47A-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 | Cathode | passive | Cathode terminal marked by the band on the unidirectional P6SMB47A, connected to the positive side of the protected line; VWM 40.2 V, VBR 44.7 V to 49.4 V at 1.0 mA, VC 64.8 V at IPPM 9.3 A. |
| 2 | Anode | passive | Anode terminal of the unidirectional P6SMB47A, connected to the return or ground side; rated for 600 W peak pulse power with a 10/1000 μs waveform. |
