PESD5V0U1UA

JSMSEMI · IC · SOD-323

PESD5V0U1UA from JSMSEMI, in a SOD-323. 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 K passive Cathode of the unidirectional ESD protection diode, connected to the line to be protected (marking bar indicates the cathode); reverse standoff voltage VRWM is 5 V max.
2 A passive Anode of the ESD protection diode, connected to ground; ESD rating is 9 kV IEC 61000-4-2 contact discharge measured from pin 1 to pin 2.
