ESD73031N-2

WILLSEMI(Will Semicon) · Electrostatic And Surge Protection (TVS/ESD) · DFN1006-2L

ESD73031N-2 from WILLSEMI(Will Semicon), in a DFN1006-2L. 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 Pin1 passive Pin 1 is one terminal of the single bidirectional protected line, which is rated for a 5.0 V maximum reverse working voltage (VRWM) and ±30 kV contact-discharge ESD per IEC61000-4-2.
2 Pin2 passive Pin 2 is the other terminal of the single bidirectional protected line, which is rated for a 5.0 V maximum reverse working voltage (VRWM) and 11 A peak pulse current (8/20 µs) per IEC61000-4-5.
