TUSD03FBX

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

TUSD03FBX 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 I/O 1 passive Bi-directional TVS terminal 1 connected to the protected power or data line; reverse working voltage 3.3V max, ±30kV IEC 61000-4-2 ESD, 1 pF typical capacitance.
2 I/O 2 passive Bi-directional TVS terminal 2, the opposite terminal (typically ground/return side); the device is symmetrical with 4V to 6V breakdown at 1mA.
