Vishay Intertech · TVS · SMB(DO-214AA)
P6SMB47CA-M3 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 | First terminal of the bidirectional TVS (CA suffix); electrical characteristics apply in both directions, there is no cathode band, and VWM is 40.2 V with VBR 44.7 V to 49.4 V at 1 mA for the 47CA type. |
| 2 | A2 | passive | Second terminal of the bidirectional TVS (CA suffix); interchangeable with the first terminal since there is no polarity marking, with a 600 W peak pulse rating on a 10/1000 μs waveform. |
