SMCJ190CA from Liown, in a SMC(DO-214AB). 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 | Terminal 1 | passive | Bidirectional (CA) TVS terminal with no polarity; the datasheet's bi-directional symbol shows two unlabeled, interchangeable terminals, with 190V reverse stand-off and 308V max clamping at 4.8A IPP. |
| 2 | Terminal 2 | passive | Bidirectional (CA) TVS terminal with no polarity; the datasheet's bi-directional symbol shows two unlabeled, interchangeable terminals, with 190V reverse stand-off and 308V max clamping at 4.8A IPP. |
