X0405C

FUXINSEMI · TRIACs · TO-126-3

X0405C from FUXINSEMI, in a TO-126-3. 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 of the SCR (K1), the return terminal for the on-state current and gate drive.
2 A passive Anode of the SCR (A2), which blocks VDRM/VRRM of 600/800 V and carries up to 4.0 A RMS on-state current.
3 G input Gate trigger input (G3) with IGT of 10 to 200 μA max at VD=12 V and VGT max 0.8 V.
