1SS181

hongjiacheng · Switching Diodes · SOT-23

1SS181 from hongjiacheng, 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 A1 passive Anode of the first diode; the function diagram shows it opposite the common pin 3, within an 80 V, 100 mA fast switching diode.
2 A2 passive Anode of the second diode; the function diagram shows it opposite the common pin 3, within an 80 V, 100 mA fast switching diode.
3 K passive Common cathode of the two diodes in the dual-diode function diagram.
