# TPDRTR5V0U4S

**TECH PUBLIC** · ESD And Surge Protection (TVS/ESD) · SOT-363

TPDRTR5V0U4S from TECH PUBLIC, in a SOT-363. 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 | IO1 | passive | ESD-protected high-speed I/O channel, protected to IEC 61000-4-2 ±18kV air/±14kV contact with 1.3pF typical capacitance to ground. |
| 2 | GND | power_in | Ground reference of the TVS array; pin 5 to pin 2 is the supply/reverse stand-off path (5V max working voltage). |
| 3 | IO2 | passive | ESD-protected high-speed I/O channel, protected to IEC 61000-4-2 ±18kV air/±14kV contact with 1.3pF typical capacitance to ground. |
| 4 | IO3 | passive | ESD-protected high-speed I/O channel, protected to IEC 61000-4-2 ±18kV air/±14kV contact with 1.3pF typical capacitance to ground. |
| 5 | VDD | power_in | Positive supply/power line protected by the internal TVS, with 5V reverse stand-off, 6V to 9V breakdown at 1mA, and 6V absolute maximum VDD-GND. |
| 6 | IO4 | passive | ESD-protected high-speed I/O channel, protected to IEC 61000-4-2 ±18kV air/±14kV contact with 1.3pF typical capacitance to ground. |
