PESD5V0U1UB 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 | Protected line pin of the single-line TVS diode (Pin1-Pin2 is the 5V working direction, breakdown tested at IT=1mA, 5.6V min). |
| 2 | Pin2 | passive | Second terminal of the single-line TVS diode, with reverse leakage tested at VRWM=5V (Pin2-Pin1) at 0.6µA typ and 5µA max. |
