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. |
