TPE05H3S4

TECH PUBLIC · ESD And Surge Protection (TVS/ESD) · SOT-143

TPE05H3S4 from TECH PUBLIC, in a SOT-143. 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 GND power_in Common anode ground node of the unidirectional TVS array, to which the three I/O protection diodes return (VRWM 5.5V any I/O pin to ground).
2 I/O1 passive Protected I/O line (TVS cathode) with VRWM 5.5V, VBR 6V at 1mA and VC 15V at IPP = 1A (8x20µs) to ground.
3 I/O2 passive Protected I/O line (TVS cathode) with VRWM 5.5V, VBR 6V at 1mA and VC 15V at IPP = 1A (8x20µs) to ground.
4 I/O3 passive Protected I/O line (TVS cathode) with VRWM 5.5V, VBR 6V at 1mA and VC 15V at IPP = 1A (8x20µs) to ground.

CAD (KiCad official)

  • Symbol: TPE05H3S4
  • Footprint: Package_TO_SOT_SMD:SOT-143
  • 3D model: SOT-143 (KiCad packages3D, STEP)
  • 3D model files: tpe05h3s4-etched.step / tpe05h3s4-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); tpe05h3s4.step / tpe05h3s4.glb are the bare package body.
