ESD05V14T-LC

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

ESD05V14T-LC 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 node of the diode array (bottom rail in the schematic), the reference for the IO-to-GND junction capacitance of 0.8 pF typ and 0.9 pF max.
2 IO1 passive Protected I/O line steered by the diode pair to the pin 4 and pin 1 rails, rated 5 V max reverse working voltage, ±30 kV IEC 61000-4-2 air and contact ESD.
3 IO2 passive Protected I/O line steered by the diode pair to the pin 4 and pin 1 rails, with 0.3 pF typ IO-to-IO junction capacitance and 5 V max reverse working voltage.
4 VCC power_in Top rail of the diode array, connected to the cathode of the TVS diode whose anode goes to pin 1, with 6.5 V min breakdown at 1 mA and 5 V max reverse working voltage.
