TPST236A054U 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 data line pin, rated for 5V reverse working voltage to ground and 0.3pF typical I/O-to-I/O capacitance. |
| 2 | GND | power_in | Ground reference of the TVS array, connected to the anode of the internal Zener; I/O pins are specified relative to it. |
| 3 | I/O2 | passive | ESD-protected data line pin, rated for 5V reverse working voltage to ground and 0.3pF typical I/O-to-I/O capacitance. |
| 4 | I/O3 | passive | ESD-protected data line pin, rated for 5V reverse working voltage to ground and 0.3pF typical I/O-to-I/O capacitance. |
| 5 | VCC | power_in | Power line protection pin connected to the internal Zener cathode (shown at the top rail); the datasheet specifies 18V max clamping at IPP=17A for VCC to ground. |
| 6 | I/O4 | passive | ESD-protected data line pin, rated for 5V reverse working voltage to ground and 0.3pF typical I/O-to-I/O capacitance. |
