TECH PUBLIC · ESD And Surge Protection (TVS/ESD) · 0402
TPESD8L3.3CT5G from TECH PUBLIC, in a 0402. 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 | Bi-directional TVS terminal 1 (pin 1 is marked by the chamfered pad), with reverse working voltage 3.3V max and junction capacitance of 0.3pF typ (0.5pF max) between pin 1 and pin 2. |
| 2 | 2 | passive | Bi-directional TVS terminal 2, interchangeable in polarity with pin 1, protecting against ±20kV air / ±15kV contact ESD per IEC 61000-4-2. |
