ESDSR05

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

ESDSR05 from Yint, 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 of the low-voltage TVS diode; in the USB example it is tied to ground.
2 I/O passive Protected I/O line steered by the low capacitance diodes (4 pF typical; 0.7 pF typ, 2.5 pF max at VR=0V, 1MHz), absorbing up to 25A (tp=8/20μs).
3 I/O passive Protected I/O line steered by the low capacitance diodes (4 pF typical; 0.7 pF typ, 2.5 pF max at VR=0V, 1MHz), absorbing up to 25A (tp=8/20μs).
4 REF passive Reference pin on the TVS cathode side (VRWM 5 V), connected to VBus/Vcc in the application examples.
