HESDNC7VB1AF-A 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 | Terminal 1 of the bidirectional ESD protection line; the datasheet rates the device for IEC61000-4-2 Level 4 ESD (±15 kV contact, ±20 kV air) and IEC61000-4-4 EFT (40 A), and gives VRWM of 7.0 V. |
| 2 | 2 | passive | Terminal 2 of the bidirectional ESD protection line; the datasheet rates the device for IEC61000-4-2 Level 4 ESD (±15 kV contact, ±20 kV air) and IEC61000-4-4 EFT (40 A), and gives VRWM of 7.0 V. |
