PESD3V3S1BA-ES

ElecSuper · ESD And Surge Protection (TVS/ESD) · SOD-323

PESD3V3S1BA-ES from ElecSuper, 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 IO1 bidirectional Connects to the protected bi-directional data line (IO1); all pins are rated to withstand ±30kV IEC 61000-4-2 contact and air discharge with a 3.3V reverse working voltage.
2 IO2 bidirectional Connects to the protected bi-directional data line (IO2); all pins are rated to withstand ±30kV IEC 61000-4-2 contact and air discharge with a 3.3V reverse working voltage.
