PTVSHC3D7VU 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 | Terminal 1 of the single-line SOD-323 TVS diode (7V VRWM, 1100W peak pulse power at tp=8/20μs); the datasheet does not state its polarity or function. |
| 2 | Pin2 | passive | Terminal 2 of the single-line SOD-323 TVS diode (7V VRWM, 1100W peak pulse power at tp=8/20μs); the datasheet does not state its polarity or function. |
