**TECH PUBLIC** · ESD And Surge Protection (TVS/ESD) · SOT-23-6

PDWL050019-SOT236 from TECH PUBLIC, in a SOT-23-6. 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 | CH1 | passive | TVS protection channel 1 (I/O pin) with 0.35 pF typical I/O-to-I/O capacitance and 5 V max reverse working voltage to ground. |
| 2 | VN | power_in | Negative/ground reference of the TVS array, to which the I/O pins are clamped. |
| 3 | CH2 | passive | TVS protection channel 2 (I/O pin) with 0.35 pF typical I/O-to-I/O capacitance and 5 V max reverse working voltage to ground. |
| 4 | CH4 | passive | TVS protection channel 4 (I/O pin) with 0.35 pF typical I/O-to-I/O capacitance and 5 V max reverse working voltage to ground. |
| 5 | VP | passive | Power line protection pin of the TVS array, with an internal TVS diode to VN. |
| 6 | CH3 | passive | TVS protection channel 3 (I/O pin) with 0.35 pF typical I/O-to-I/O capacitance and 5 V max reverse working voltage to ground. |
