TPESDR0502BT1G

TECH PUBLIC · ESD And Surge Protection (TVS/ESD) · SOT-523

TPESDR0502BT1G from TECH PUBLIC, in a SOT-523. 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 IO1 passive TVS diode array I/O line 1 protected channel, 5V max reverse working voltage, 0.5pF typ (0.6pF max) capacitance to GND.
2 IO2 passive TVS diode array I/O line 2 protected channel, 5V max reverse working voltage, 0.5pF typ (0.6pF max) capacitance to GND.
3 GND power_in Common ground connection of the TVS diode array, shared by both I/O protection diodes.

CAD (KiCad official)

  • Symbol: TPESDR0502BT1G
  • Footprint: Package_TO_SOT_SMD:SOT-523
  • 3D model: SOT-523, generated from the KiCad footprint (body from the F.Fab outline, terminals on the pads, 0.8 mm nominal SOT-523 height). Neither the vendor nor KiCad ships a 3D model for this package, so the dimensions are nominal, not the manufacturer's CAD (STEP)
  • 3D model files: tpesdr0502bt1g-etched.step / tpesdr0502bt1g-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); tpesdr0502bt1g.step / tpesdr0502bt1g.glb are the bare package body.
