SMCJ15A-L from Shandong Jingdao Microelectronics, in a 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 | Cathode terminal of the unidirectional TVS diode; the datasheet PINNING table assigns pin 1 to the cathode for the unipolar (A-suffix) SMCJ-L parts, of which SMCJ15A-L is one. |
| 2 | Anode | passive | Anode terminal of the unidirectional TVS diode, which the datasheet PINNING table assigns to pin 2 for the unipolar (A-suffix) SMCJ-L parts. |
