ESD5B5.0ST1G from UMW, in a SOD-523. 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 | Pin1 | passive | The pinning information for the SOD-523 package labels this terminal only as Pin1, and the datasheet does not state its function or polarity (anode or cathode). |
| 2 | Pin2 | passive | The pinning information for the SOD-523 package labels this terminal only as Pin2, and the datasheet does not state its function or polarity (anode or cathode). |
