PESD3V3L2BT 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 the first bidirectional ESD protection diode; clamping and ESD ratings are measured from pin 1 to pin 3 (IPPM = 15 A, VCL = 26 V, IEC 61000-4-2 contact discharge up to 30 kV). |
| 2 | K2 | passive | Cathode of the second bidirectional ESD protection diode; clamping and ESD ratings are measured from pin 2 to pin 3 (IPPM = 15 A, VCL = 26 V, IEC 61000-4-2 contact discharge up to 30 kV). |
| 3 | CC | passive | Double cathode (common terminal) shared by the two protection diodes; all pin 1 to 3 and pin 2 to 3 limiting values and characteristics refer to this pin. |
