ESD9N18BA-2

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

ESD9N18BA-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 Terminal 1 of the 1-line bidirectional TVS, labeled Pin1 in the circuit diagram and bottom view; the datasheet gives no per-pin function or limit beyond the device ratings (stand-off ±18V max, ±30kV contact ESD per IEC61000-4-2).
2 Pin2 passive Terminal 2 of the 1-line bidirectional TVS, labeled Pin2 in the circuit diagram and bottom view; the datasheet gives no per-pin function or limit beyond the device ratings (stand-off ±18V max, ±30kV contact ESD per IEC61000-4-2).
