ESD3V3B20A-1006 from TECH PUBLIC, 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 ESD protection line terminal (pin 1, marked with the chamfered pad); the device has 3.3V max reverse working voltage and 30pF typical junction capacitance between pin 1 and pin 2. |
| 2 | 2 | passive | Bi-directional ESD protection line terminal (pin 2); the device has 3.3V max reverse working voltage and 30pF typical junction capacitance between pin 2 and pin 1. |
