TPD2E009DBZR

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

TPD2E009DBZR 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 CH1 passive ESD/TVS protected channel 1 (steering diode pair to the central TVS diode), 5V max reverse working voltage, 0.5pF typ to GND, 0.35pF typ IO to IO.
2 CH2 passive ESD/TVS protected channel 2 (steering diode pair to the central TVS diode), 5V max reverse working voltage, 0.5pF typ to GND, 0.35pF typ IO to IO.
3 CH3 passive Common pin labelled CH3, connected to the central TVS diode and the steering diodes in the pin configuration diagram; the datasheet does not name it GND explicitly.

  • Symbol: TPD2E009DBZR
  • Footprint: Package_TO_SOT_SMD:SOT-23
  • 3D model: SOT-23 (KiCad packages3D, STEP)
  • 3D model files: tpd2e009dbzr-etched.step / tpd2e009dbzr-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); tpd2e009dbzr.step / tpd2e009dbzr.glb are the bare package body.
