HXY MOSFET · ESD And Surge Protection (TVS/ESD) · DFN1006-2L
HDESD3V3E1BL-7B from HXY MOSFET, 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 | 1 | passive | One terminal of the single bi-directional line this ESD protection device clamps; the datasheet gives no polarity for this terminal because the device is bi-directional. |
| 2 | 2 | passive | The other terminal of the single bi-directional line this ESD protection device clamps; the datasheet gives no polarity for this terminal because the device is bi-directional. |
