SMBJ5340B-TP from MCC(Micro Commercial Components), 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 (marked with the cathode band); the 6 V ±5% zener voltage is regulated at IZT = 200 mA with ZZT max 1 ohm, IR max 1 µA at VR = 3 V, and IZM max 790 mA. |
| 2 | A | passive | Anode; forward voltage VF is 1.2 V max at 1.0 A, and steady-state power dissipation is 5 W with lead temperature at 75°C. |
