TPESD03K2WT

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

TPESD03K2WT from TECH PUBLIC, in a SOD-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 Pin 1 passive One of two ESD protection terminals of the bidirectional (back-to-back) TVS diode; the datasheet gives a reverse working voltage VRWM of 3.3 V max and a reverse leakage current of 500 nA max at VRWM = 3.3 V.
2 Pin 2 passive The other ESD protection terminal of the bidirectional TVS diode; the datasheet gives a reverse working voltage VRWM of 3.3 V max and a junction capacitance of 0.5 pF max at VR = 0 V, f = 1 MHz.

  • Symbol: TPESD03K2WT
  • Footprint: Diode_SMD:D_SOD-523
  • 3D model: SOD-523 (KiCad packages3D, STEP)
  • 3D model files: tpesd03k2wt-etched.step / tpesd03k2wt-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); tpesd03k2wt.step / tpesd03k2wt.glb are the bare package body.
