Nexperia · ESD And Surge Protection (TVS/ESD) · SOT-23
PESD5V0X1BT 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 diode 1; in bidirectional use, the protected line connects to pin 1 and the bidirectional path is measured from pin 1 to pin 2 or pin 2 to pin 1. |
| 2 | K2 | passive | Cathode of diode 2; in bidirectional use, the protected line connects to pin 2 and the bidirectional path is measured from pin 2 to pin 1 or pin 1 to pin 2. |
| 3 | CA | passive | Common anode shared by both diodes; in unidirectional use, capacitance is measured from pin 1 to pin 3 or pin 2 to pin 3, and this pin is the ground-side connection. |
