SMCJ43A-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 unipolar SMCJ43A-L TVS diode; the datasheet gives the 43 V reverse stand-off and clamping ratings between this pin and the anode. |
| 2 | Anode | passive | Anode terminal of the unipolar SMCJ43A-L TVS diode; the datasheet gives the 43 V reverse stand-off and clamping ratings between this pin and the cathode. |
