**Applied Power** · TVS · DFN1006-2

AR0821P1 from Applied Power, in a DFN1006-2. 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 | Bi-directional TVS terminal (pin 1); line-protection connection with 8V reverse working voltage, interchangeable with pin 2 as the device is symmetric. |
| 2 | 2 | passive | Bi-directional TVS terminal (pin 2); line-protection connection with 8V reverse working voltage, interchangeable with pin 1 as the device is symmetric. |
