SMDJ17A

Brightking Elec (TAIWAN) · TVS · SMC(DO-214AB)

SMDJ17A from Brightking Elec (TAIWAN), in a SMC(DO-214AB). 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 of the unidirectional TVS (marked by the color band), connected to the positive side of the protected line, with VRWM 17.0V, VBR 18.90~20.90V at 1mA and VC 27.6V at 108.7A IPP.
2 A passive Anode of the unidirectional TVS (no band), connected to the ground/return side of the protected line, with peak forward surge current IFSM of 300A.
