SMA6J10CA-TR from STMicroelectronics, in a SMA(DO-214AC). 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 | Terminal labeled K in the bidirectional SMA drawing; for the CA type the two terminals are interchangeable, with no polarity band and surge capability in both directions. |
| 2 | A | passive | Terminal labeled A in the bidirectional SMA drawing; for the CA type the two terminals are interchangeable, with no polarity band and surge capability in both directions. |
