TPE1272BS3

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

TPE1272BS3 from TECH PUBLIC, 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 Line 1 protected I/O (bi-directional TVS to Pin 3), reverse working voltage 12V max, breakdown 13.6V min to 17.5V max at 1mA.
2 PIN2 passive Line 2 protected I/O (bi-directional TVS to Pin 3), reverse working voltage 12V max, clamping 10V max at Ipp=8A (8/20µs).
3 PIN3 passive Common node of both TVS diodes shared by Pin 1 and Pin 2, typically tied to ground/reference; ESD rating ±30kV air and contact.
