S1DL

Changjing · Diodes - General Purpose · SOD-123FL

S1DL from Changjing, 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 K passive Cathode, marked by the color band on the package; positive terminal of the rectifier diode for conduction in reverse polarity (DL: 200V VRRM, 1.0A IF(AV)).
2 A passive Anode terminal of the rectifier diode; forward current up to 1.0A average, with VF specified at IF=1.0A.
