PSD03C

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

PSD03C from FUXINSEMI, 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 One terminal of the bi-directional TVS diode that protects one bi-directional I/O line, with 3.3 V working voltage and 450 W peak pulse power per line (tp=8/20µs).
2 I/O 2 passive The other terminal of the bi-directional TVS diode that protects one bi-directional I/O line, with 3.3 V working voltage and 450 W peak pulse power per line (tp=8/20µs).
