PTVSHC3D4V5B 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 | 1 | passive | Terminal 1 of the single-line ESD protector, referenced as Pin1 in the Pin1-to-Pin2 breakdown (4.6 V min at 1 mA), leakage (2 µA max at VRWM = 4.5 V) and clamping specifications. |
| 2 | 2 | passive | Terminal 2 of the single-line ESD protector, referenced as Pin2 in the Pin1-to-Pin2 breakdown, leakage and clamping specifications; the PCB guidance says the anode goes to ground through short, low-inductance vias. |
