SMBJ33A-13-F from Diodes Incorporated, in a SMB. 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 unidirectional SMBJ33A; connects to the protected line, which is held off to VRWM 33.0V and clamped at max 53.3V at 11.3A. |
| 2 | A | passive | Anode terminal of the unidirectional SMBJ33A, normally connected to ground or the return side of the protected line. |
