PESD2IVN-UX 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 | K | passive | Cathode K of the first in-vehicle network line; the surge and ESD ratings are measured from this pin to pin 3. |
| 2 | K | passive | Cathode K of the second in-vehicle network line; the surge and ESD ratings are measured from this pin to pin 3. |
| 3 | CC | passive | Common cathode CC, the reference terminal for pins 1 and 2, rated for IPPM 3 A at tp = 8/20 µs and VESD 18 kV contact discharge. |
