SMF170A_R1_00001

PANJIT International · TVS · SOD-123FL

SMF170A_R1_00001 from PANJIT International, in a SOD-123FL. 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 Cathode passive Cathode terminal of the unidirectional TVS, marked by the color band; connect to the protected positive line (VRWM 170 V, VBR 189 to 209 V at 1 mA, VC 275 V at 0.6 A).
2 Anode passive Anode terminal of the unidirectional TVS, normally connected to ground/return; peak pulse power 200 W at tp=10/1000μs.
