**TECH PUBLIC** · ESD Protection Devices · SOT-23

TPE0572BS3-A 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 | 1 | passive | Protected line 1 of the bi-directional TVS pair, with reverse working voltage 5 V max and junction capacitance to pin 3 of 15 pF typ and 20 pF max (VR=0, f=1MHz). |
| 2 | 2 | passive | Protected line 2 of the bi-directional TVS pair, with reverse working voltage 5 V max and junction capacitance to pin 3 of 15 pF typ and 20 pF max (VR=0, f=1MHz). |
| 3 | 3 | passive | Common node shared by both diode pairs, with 15 pF typ and 20 pF max capacitance to pin 1 or pin 2 (VR=0, f=1MHz). |
