SMF170A

AnBon · ESD And Surge Protection (TVS/ESD) · SOD-123

SMF170A from AnBon, in a SOD-123. 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 K passive Cathode of the unidirectional TVS, marked by the cathode band; SMF170A has VRWM 170 V, VBR 189 V min to 209 V max at 1.0 mA, and VC 275 V at Ipp 0.8 A.
2 A passive Anode of the unidirectional TVS; the 200 W peak pulse power (10x1000us) device protects one I/O line.
