WILLSEMI(Will Semicon) · ESD Protection Devices · DFN1006-2L
ESD56371N-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 | One of two terminals of the bi-directional TVS, which protects the line against ESD of ±30kV (contact and air, IEC61000-4-2) and 22A surge (8/20μs, IEC61000-4-5) with a reverse stand-off voltage of ±15V Max. |
| 2 | Pin2 | passive | The second terminal of the bi-directional TVS, which protects the line against ESD of ±30kV (contact and air, IEC61000-4-2) and 22A surge (8/20μs, IEC61000-4-5) with a reverse stand-off voltage of ±15V Max. |
