ESDU5V0G3

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

ESDU5V0G3 from Changjing, 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 pin of the ESD protection diode, with I/O-to-GND reverse standoff voltage of 5 V (VRWM) and forward voltage of 0.4 to 1.5 V (typ to max) at IF=10 mA from GND to I/O.
2 I/O passive Protected line input/output (channel 2), clamped to GND with VRWM 5 V, leakage 1 µA max at 5 V, and 0.8 pF max capacitance (0.4 pF max I/O to I/O).
3 I/O passive Protected line input/output (channel 1), clamped to GND with VRWM 5 V, leakage 1 µA max at 5 V, and 0.8 pF max capacitance (0.4 pF max I/O to I/O).
4 VCC power_in Supply/rail steering pin (VCC or VDD) protected to GND with breakdown voltage 5 to 12 V at IT=1 mA and clamping voltage 13 V at IPP=1 A and 25 V at IPP=3.5 A.
