PESD2IVN27U-QX from Nexperia, 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 | K1 | passive | Cathode of diode 1, one of the two protected bus lines; the datasheet measures clamping voltage from pin 1 to pin 3 (VCL = 36 V typical at IPPM = 3 A, tp = 8/20 µs). |
| 2 | K2 | passive | Cathode of diode 2, the second protected bus line; the datasheet measures clamping voltage from pin 2 to pin 3 (same test conditions as pin 1). |
| 3 | K | passive | Common cathode shared by both ESD protection diodes, serving as the reference terminal for the clamping measurements on pins 1 and 2. |
