SMBJ5369B-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 terminal, identified by the cathode band on the package marking; the SMBJ5369B has a nominal VZ of 51V at 25mA test current. |
| 2 | A | passive | Anode terminal, opposite the cathode band; the device is rated 5W steady-state dissipation with a 1.2V maximum forward voltage at 1.0A. |
