SMAJ5.0CA-MS from MSKSEMI, 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 | A1 | passive | Bidirectional TVS terminal (SMAJ5.0CA-MS: VR 5.0 V stand-off, VBR 6.40-7.00 V at 10 mA, VC 9.2 V max at 43.48 A IPP); no cathode band, either terminal may be the more positive. |
| 2 | A2 | passive | Bidirectional TVS terminal (SMAJ5.0CA-MS: VR 5.0 V stand-off, VBR 6.40-7.00 V at 10 mA, VC 9.2 V max at 43.48 A IPP); datasheet says the color band denotes cathode except on bi-directional models. |
