TPSMF4L26A

Littelfuse · TVS · SOD-123FL

TPSMF4L26A from Littelfuse, in a SOD-123FL. 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 uni-directional TVS diode, marked by the color/cathode band on the package, connects to the protected positive line (VR 26 V standoff, VBR 28.90-31.90 V at 1 mA).
2 A passive Anode of the uni-directional TVS diode, the side opposite the cathode band, typically connected to ground (max clamping voltage 42.1 V at 9.5 A Ipp).

CAD (KiCad official)

  • Symbol: TPSMF4L26A
  • Footprint: Diode_SMD:D_SOD-123F
  • 3D model: SOD-123FL (KiCad packages3D, STEP)
  • 3D model files: tpsmf4l26a-etched.step / tpsmf4l26a-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); tpsmf4l26a.step / tpsmf4l26a.glb are the bare package body.
