ESD3V3B03-323

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

ESD3V3B03-323 from TECH PUBLIC, 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 1 passive Bi-directional TVS terminal 1; protects one power or data line, 3.3V max reverse working voltage, ±15kV contact / ±20kV air ESD per IEC 61000-4-2.
2 2 passive Bi-directional TVS terminal 2; either terminal may connect to the protected line or to ground since the diode is symmetric, 3.3V max reverse working voltage.
