BTW69-1200B

KY · TRIACs · TO-3P

BTW69-1200B from KY, in a TO-3P. 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, the return terminal for on-state current (IT(RMS) 55 A max) and gate current.
2 A passive Anode of the SCR, which blocks up to VDRM/VRRM of 1200 V for the BTW69-1200B and carries on-state current of 55 A RMS max.
3 G input Gate trigger input, which turns the SCR on with VGT up to 1.5 V and IGT up to 70 mA at VD=12 V.

CAD (KiCad official)

  • Symbol: BTW69-1200B
  • Footprint: Package_TO_SOT_THT:TO-3P-3_Vertical
  • 3D model: TO-3P (KiCad packages3D, STEP)
  • 3D model files: btw69-1200b-etched.step / btw69-1200b-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); btw69-1200b.step / btw69-1200b.glb are the bare package body.
