# TPSP0504SHTG

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

TPSP0504SHTG 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/O 1 | passive | TVS-protected data line 1; reverse working voltage 5V max to ground, 0.3pF typical I/O-to-I/O capacitance. |
| 2 | GND | power_in | Ground reference for the TVS array; I/O clamping voltage is specified to this pin. |
| 3 | I/O 2 | passive | TVS-protected data line 2; reverse working voltage 5V max to ground, ESD rated ±25kV air and ±20kV contact. |
| 4 | I/O 3 | passive | TVS-protected data line 3; reverse working voltage 5V max to ground, 0.8pF max capacitance to ground. |
| 5 | Vcc | power_in | Power line protection pin; the TVS is rated 300W peak pulse power (8/20µs, Vcc-GND) and clamps 18V max at 17A. |
| 6 | I/O 4 | passive | TVS-protected data line 4; reverse working voltage 5V max to ground, 4.7A peak pulse current (8/20µs). |
