TPST236A054U

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

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.
