PESD2ETH100T-QR from Nexperia, in a SOT-23. 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 protection diode K1, connected to one bus line (e.g. BI_DA+) and rated for 30 kV IEC 61000-4-2 contact discharge measured to pin 3 with VRWM 24 V max. |
| 2 | K2 | passive | Cathode of protection diode K2, connected to the other bus line (e.g. BI_DA-) and rated for 30 kV IEC 61000-4-2 contact discharge measured to pin 3 with VRWM 24 V max. |
| 3 | CC | passive | Common cathode, the reference for ESD and surge measurements from pins 1 and 2, with Cd typically 2.5 pF (3 pF max) per line. |
