ESDBW712C2

Changjing · ESD And Surge Protection (TVS/ESD) · SOT-23

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).
