**TECH PUBLIC** · ESD Protection Devices · SOT-23-6

TPPRTR5V0U2D 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 | I/O1 | passive | ESD-protected I/O line 1, internally connected to pin 6 (steering diodes to VBUS and GND); 5V operating voltage, 0.35 pF typ IO-to-IO capacitance. |
| 2 | GND | power_in | Ground reference for the TVS diode array. |
| 3 | I/O2 | passive | ESD-protected I/O line 2, internally connected to pin 4 (steering diodes to VBUS and GND); 5V operating voltage, ±30kV air/contact ESD per IEC 61000-4-2. |
| 4 | I/O2 | passive | ESD-protected I/O line 2, internally connected to pin 3; 5V reverse working voltage max. |
| 5 | VBUS | power_in | Supply/bus rail connection of the TVS array, with 5V max reverse working voltage and 6V min breakdown at 1mA. |
| 6 | I/O1 | passive | ESD-protected I/O line 1, internally connected to pin 1; clamping voltage 15V max at 1A and 24V max at 6A (8/20µs). |
