SMBJ13A from hongjiacheng, in a DO-214AA(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 terminal, marked by the cathode band on the unidirectional SMBJ13A, which connects to the protected line and has VRWM 13.0 V, VBR 14.40 to 15.90 V at 1 mA and VC 21.5 V at IPP 27.91 A. |
| 2 | A | passive | Anode terminal, the end without the cathode band, which connects to ground or the return side and conducts in the forward direction with VF 3.5 V at 25 A for a unidirectional part. |
