YFW · ESD And Surge Protection (TVS/ESD) · 0201
PESD0201B18 from YFW, in a 0201. 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 | Bidirectional ESD protection terminal connected to the signal line to be protected; the device is symmetric, so pins 1 and 2 are interchangeable, rated 18.0 V max continuous operating voltage. |
| 2 | 2 | passive | Second bidirectional ESD protection terminal, typically connected to GND, with 8 kV contact and 15 kV air discharge (IEC 61000-4-2) ratings. |
