SMDJ12CA from YFW, in a DO-214AB(SMC). 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 | Cathode | passive | TVS terminal 1, labelled cathode in the datasheet pinning; on the bidirectional SMDJ12CA it has no polarity: VRWM 12.0V, VBR 13.3-14.7V at IT=1mA, VC max 19.9V at IPP 150.8A, IR max 2uA, PPPM 3000W (10x1000us). |
| 2 | Anode | passive | TVS terminal 2, labelled anode in the datasheet pinning; on the bidirectional SMDJ12CA it is interchangeable with pin 1 and clamps symmetrically at VC max 19.9V at IPP 150.8A. |
