SMBJ28CA-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 | A1 | passive | Bi-directional (C suffix) TVS terminal with no polarity indicator, so either terminal may connect to the protected line; standoff voltage VRWM 28.0V, clamping 45.4V at 13.2A. |
| 2 | A2 | passive | Second bi-directional TVS terminal with no cathode band, interchangeable with the other terminal; 600W peak pulse power rating. |
