Littelfuse · TVS · DO-214AA
P6SMB12CA from Littelfuse, in a 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 | Bidirectional TVS terminal with no polarity (P6SMB12CA, VR 10.20V, VBR 11.40V typ at 1mA, max VC 16.7V at 36.5A Ipp); either terminal may connect to the protected line. |
| 2 | A2 | passive | Bidirectional TVS terminal with no polarity (P6SMB12CA, 600W peak pulse power at 10/1000µs); the cathode band is absent on bidirectional versions. |
