TPSP0502BAHTG

TECH PUBLIC · ESD And Surge Protection (TVS/ESD) · SOT-23

TPSP0502BAHTG from TECH PUBLIC, in a SOT-23. 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 I/O1 passive Protected line 1 (TVS diode anode side per schematic); working voltage 5V, VRWM max 5.5V, with 30pF typ capacitance to pin 2 and 60pF typ to pin 3.
2 I/O2 passive Protected line 2 (TVS diode anode side per schematic); working voltage 5V, VRWM max 5.5V, with 30pF typ capacitance to pin 1 and 60pF typ to pin 3.
3 GND power_in Common connection of both TVS diodes (ground/reference) shared by pins 1 and 2; the datasheet schematic shows it only as pin 3.

  • Symbol: TPSP0502BAHTG
  • Footprint: Package_TO_SOT_SMD:SOT-23
  • 3D model: SOT-23 (KiCad packages3D, STEP)
  • 3D model files: tpsp0502bahtg-etched.step / tpsp0502bahtg-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); tpsp0502bahtg.step / tpsp0502bahtg.glb are the bare package body.
