SMDJ13A 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 SMDJ13A TVS diode (SMC package); for the bipolar version the pin is interchangeable with the other terminal. |
| 2 | Anode | passive | Anode terminal of the unidirectional SMDJ13A TVS diode (SMC package), which clamps at max 21.5 V at 139.5 A peak pulse current. |
