P6KE43A

Brightking Elec (TAIWAN) · TVS · DO-204AC(DO-15)

P6KE43A from Brightking Elec (TAIWAN), in a DO-204AC(DO-15). 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, marked by the color band on the unidirectional P6KE43A; it connects to the positive side of the circuit, with VRWM 36.8V, VBR 40.90~45.20V at 1mA and VC 59.3V at IPP 10.3A.
2 A passive Anode, the end opposite the color band on the unidirectional P6KE43A; it connects to the negative or ground side, with a peak forward surge current rating (IFSM) of 100A.
