NUP2125WTT1G 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 | PIN 1 | passive | Protected CAN bus line 1 (bidirectional TVS path to common pin 3), reverse working voltage 24V max, ESD ±30kV air/contact per IEC 61000-4-2. |
| 2 | PIN 2 | passive | Protected CAN bus line 2 (bidirectional TVS path to common pin 3), reverse working voltage 24V max, ESD ±30kV air/contact per IEC 61000-4-2. |
| 3 | PIN 3 | passive | Common pin joining the back-to-back diode pairs of pins 1 and 2 as shown in the schematic; the datasheet does not label it as ground. |
