SMBJ5344B from LGE, in a SMB(DO-214AA). 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 end marked with the color band; the Zener is reverse biased with this pin positive, VZ 8.2 V nominal at IZT 150 mA for the SMBJ5344 type. |
| 2 | A | passive | Anode, the end opposite the color band; 5 W maximum power dissipation at TL = 25 °C and VF 1.2 V maximum at IF = 1.0 A. |
