ESD9L3.3ST5GB

FUXINSEMI · ESD And Surge Protection (TVS/ESD) · DFN1006-2

ESD9L3.3ST5GB from FUXINSEMI, in a DFN1006-2. 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 One terminal of the bidirectional TVS diode, which protects one bi-directional I/O line with a 3.3 V reverse working voltage, 4.0 A peak pulse current (8/20 µs) and ±20 kV IEC 61000-4-2 air/contact ESD rating.
2 2 passive The other terminal of the bidirectional TVS diode, which protects one bi-directional I/O line with a 3.3 V reverse working voltage, 4.0 A peak pulse current (8/20 µs) and ±20 kV IEC 61000-4-2 air/contact ESD rating.
