# PTVSHC3D15VUH

**UMW** · ESD And Surge Protection (TVS/ESD) · SOD-323

PTVSHC3D15VUH 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 | One terminal of the unidirectional TVS (VRWM 15V, VBR 16V min at 1mA); the datasheet places the cathode on the signal trace and the anode to ground, but the text does not say which pin is which. |
| 2 | PIN2 | passive | Other terminal of the unidirectional TVS (VRWM 15V, VBR 16V min at 1mA); the datasheet places the cathode on the signal trace and the anode to ground, but the text does not say which pin is which. |
