**TECH PUBLIC** · Electrostatic And Surge Protection (TVS/ESD) · DFN1006-2

PTVS4V5D1BLYR from TECH PUBLIC, in a DFN1006-2. 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 1-line bi-directional TVS diode, shown as pin 1 in the pin configuration diagram; the datasheet gives a reverse working voltage (VRWM) of 4.5 V max and a reverse leakage current of 0.1 µA max at VRWM = 4.5 V. |
| 2 | 2 | passive | Terminal 2 of the 1-line bi-directional TVS diode, shown as pin 2 in the pin configuration diagram; the datasheet gives a clamping voltage of 15 V max at Ipp = 30 A (8x20 µs pulse) and a junction capacitance of 100 pF max at VR = 0 V, f = 1 MHz. |
