PESD5V2S2UT-K from PAKER, 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 | 1 | passive | Pin 1 is one of the two line pins measured against pin 3 for the 120 pF typical junction capacitance (VR = 0 V, f = 1 MHz); no pin function is stated. |
| 2 | 2 | passive | Pin 2 is one of the two line pins measured against pin 3 for the 120 pF typical junction capacitance (VR = 0 V, f = 1 MHz); no pin function is stated. |
| 3 | 3 | passive | Pin 3 is the common reference pin for the pin1/pin2 junction capacitance measurement; no other function is stated. |
