3SMAJ5929B-TP from MCC(Micro Commercial Components), in a SMA(DO-214AC). 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 | K | passive | Cathode, marked by the cathode band on the package; the 3SMAJ5929B has a 15V zener voltage at 25mA test current and is reverse biased (cathode positive) for regulation. |
| 2 | A | passive | Anode, the end opposite the cathode band; the datasheet states a forward voltage of 1.5V max at IF=200mA. |
