PESD0603B12 from YFW, in a 0603. 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; continuous operating voltage 12.0 V max, leakage current 100 nA max, capacitance 0.05 pF typ. |
| 2 | 2 | passive | Bidirectional ESD protection terminal connected to ground or the return path (the application circuit ties one side to GND); the device is symmetric with 12.0 V max operating voltage. |
