DESD3V3S1BL-7B from Diodes Incorporated, 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 | Bidirectional TVS terminal identified by the bar on the bottom view as Pin #1, protecting one channel to ±25kV contact / ±30kV air per IEC 61000-4-2 with VRWM 3.3V max. |
| 2 | 2 | passive | Second bidirectional TVS terminal, interchangeable with pin 1 for the single protected channel (VRWM 3.3V max, VBR 3.8V to 6.5V at 1mA). |
