TPESD0512S4-A

TECH PUBLIC · ESD And Surge Protection (TVS/ESD) · SOT-143

TPESD0512S4-A from TECH PUBLIC, in a SOT-143. 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 GND power_in Common ground/anode end of the TVS diode array (diagram Pin 1, bottom rail), reference for the IO-to-GND capacitance of 0.8 pF typ, 0.9 pF max at VR = 0 V, 1 MHz.
2 IO1 passive Protected line 1 (steering-diode pair midpoint, USB 2.0/data line), working voltage 5 V max, 0.08 uA max leakage at VRWM = 5 V.
3 IO2 passive Protected line 2 (steering-diode pair midpoint, USB 2.0/data line), working voltage 5 V max, 0.3 pF typ IO-to-IO capacitance at 0 V, 1 MHz.
4 VCC power_in Top rail of the diode bridge connected to the TVS diode cathode (diagram Pin 4), reverse working voltage 5 V max and breakdown 6.5 V min at 1 mA.
