# TPE0572BS3

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

TPE0572BS3 from TECH PUBLIC, in a SOT-23. 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 | I/O1 | passive | TVS protected line 1, bi-directional diode path to pin 3 with 15 pF typ (20 pF max) junction capacitance at VR=0, f=1MHz; reverse working voltage 5V max. |
| 2 | I/O2 | passive | TVS protected line 2, bi-directional diode path to pin 3 with 15 pF typ (20 pF max) junction capacitance at VR=0, f=1MHz; reverse working voltage 5V max. |
| 3 | COMMON | passive | Common node of the two TVS diode paths from pins 1 and 2 (shown joined at pin 3 in the diagram); the datasheet does not label it as ground. |
