SMBJ90A-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 | Cathode | passive | Cathode terminal of the unidirectional SMBJ90A, marked by the cathode band on the package; connect to the positive side of the protected line (VRWM 90V, VBR 100V min to 115.5V max at 1mA, VC 146V max at 4.1A). |
| 2 | A | passive | Anode terminal of the unidirectional SMBJ90A, opposite the cathode band; connect to ground or the return side of the protected line. |
