PTVSHC3D18VU
Shanghai Prisemi Elec · ESD And Surge Protection (TVS/ESD) · SOD-323
PTVSHC3D18VU from Shanghai Prisemi Elec, 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 | Unidirectional TVS terminal (cathode side per PCB guidance, placed directly on the protected signal trace) with 18V peak reverse working voltage, 20-23V breakdown at 1mA. |
| 2 | Pin2 | passive | Unidirectional TVS terminal (anode side per PCB guidance, connected to ground through close, low-inductance vias) for 1200W peak pulse power (8/20μs) protection. |
