ESD05V14T

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

ESD05V14T from DOWO, 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 Ground reference connected to the anode side of the internal TVS diode, used for I/O-GND and VCC-GND clamping (50 W/4 A I/O-GND, 8/20µs).
2 I/O1 passive Protected line 1 steering-diode node, uni-directional with 5V working voltage, 0.6pF (typ. 0.6 to 0.9pF max) I/O-GND capacitance and IEC 61000-4-2 ±15kV contact / ±20kV air.
3 I/O2 passive Protected line 2 steering-diode node, uni-directional with 5V working voltage, 0.6pF (typ. 0.6 to 0.9pF max) I/O-GND capacitance and IEC 61000-4-2 ±15kV contact / ±20kV air.
4 VCC power_in Supply-rail side of the internal TVS diode (cathode), with VCC-GND breakdown 6 to 9V at 1mA and 240W/15A peak pulse rating (8/20µs).
