3SMAJ5919B-TP from MICRO COMMERCIAL CO, in a DO-214AC(SMA). 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, the terminal on the cathode-mark (banded) end of the SMA body; it goes positive relative to the anode in Zener breakdown, with VZ = 5.6V at IZT = 66.9mA for the 3SMAJ5919B. |
| 2 | A | passive | Anode, the terminal opposite the cathode mark; maximum forward voltage is 1.5V at IF = 200mA. |
