KSM712

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

KSM712 from KUU, 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 Pin 1 passive ESD-protected line that clamps to pin 3, with reverse working voltage 12 V for pin 1 or pin 2 to pin 3 and 7 V for pin 3 to pin 1 or pin 2, and a maximum peak pulse current of 13 A (8/20 µs).
2 Pin 2 passive ESD-protected line that clamps to pin 3, with reverse working voltage 12 V for pin 1 or pin 2 to pin 3 and 7 V for pin 3 to pin 1 or pin 2, and a maximum peak pulse current of 13 A (8/20 µs).
3 Pin 3 passive Common terminal referenced by pin 1 and pin 2 in the protection specifications, with 7 V reverse working voltage for pin 3 to pin 1 or pin 2 and 12 V for pin 1 or pin 2 to pin 3.
