TOSHIBA · ESD Protection Devices · SOD-923
DF2B7AFS from TOSHIBA, in a SOD-923. 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 | Pin 1 | bidirectional | Signal/I/O pin of the ESD protection diode, with Pin 2 connected to GND when Pin 1 is used for I/O; working peak reverse voltage VRWM is at most 5.5 V. |
| 2 | Pin 2 | bidirectional | Second protection pin of the ESD diode, to be connected to GND when Pin 1 is used for I/O (and Pin 1 connected to GND when Pin 2 is used for I/O); working peak reverse voltage VRWM is at most 5.5 V. |
