FESD15BD3

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

FESD15BD3 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 bidirectional TVS diode, connected to the protected I/O line (15V reverse working voltage, 16.7V min breakdown at 1mA); polarity does not matter.
2 I/O 2 passive The other terminal of the bidirectional TVS diode, connected to ground or the return side (15V reverse working voltage, 350W peak pulse power at 8/20µs); polarity does not matter.
