ESDBW712C2 from Changjing, in a SOT-23. 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 | PIN1 | passive | One of the two bi-directional ESD-protected lines, clamped to PIN3 with a 12 V reverse standoff voltage and rated for 396 W peak pulse power (8/20 µs, PIN1/PIN2 to PIN3). |
| 2 | PIN2 | passive | The second bi-directional ESD-protected line, clamped to PIN3 with a 12 V reverse standoff voltage and rated for 396 W peak pulse power (8/20 µs, PIN1/PIN2 to PIN3). |
| 3 | PIN3 | passive | Common terminal of the bi-directional clamp, rated for 10 W peak pulse power and 15 A peak pulse current from PIN3 to PIN1/PIN2 (8/20 µs). |
