PTVSHC3D12VU from UMW, in a SOD-323. 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 | Labeled Pin1 on the datasheet's circuit diagram; the device protects one I/O or power line per line, but the datasheet does not state which terminal is the anode or cathode. |
| 2 | Pin2 | passive | Labeled Pin2 on the datasheet's circuit diagram; the device has a 12 V peak reverse working voltage and a 1300 W peak pulse power rating per line, but the datasheet does not state the polarity of this terminal. |
