TPESDB5V0AT3

TECH PUBLIC · ESD And Surge Protection (TVS/ESD) · SOT-323

TPESDB5V0AT3 from TECH PUBLIC, in a SOT-323. 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 1 passive Protected line terminal of the bi-directional TVS (5V working voltage, 6V min breakdown at 1mA), shown connected through a diode pair to common pin 3.
2 2 passive Second protected line terminal of the bi-directional TVS (5V working voltage, 6V min breakdown at 1mA), shown connected through a diode pair to common pin 3.
3 3 passive Common node of the diode pairs from pins 1 and 2 in the internal schematic; the datasheet gives no further function.

CAD (KiCad official)

  • Symbol: TPESDB5V0AT3
  • Footprint: Package_TO_SOT_SMD:SOT-323_SC-70
  • 3D model: SOT-323 (KiCad packages3D, STEP)
  • 3D model files: tpesdb5v0at3-etched.step / tpesdb5v0at3-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); tpesdb5v0at3.step / tpesdb5v0at3.glb are the bare package body.
