SMBJ13A-AT

Brightking Elec (TAIWAN) · TVS · SMB(DO-214AA)

SMBJ13A-AT from Brightking Elec (TAIWAN), 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, identified by the color band on the unidirectional SMBJ13A-AT (VRWM 13.0V, VBR 14.40~15.90V at 1mA, VC 21.5V at IPP 28.0A).
2 A passive Anode terminal of the unidirectional SMBJ13A-AT, opposite the cathode band end; the datasheet gives no pin numbers.
