1N4148WSF-7

Diodes Incorporated · Switching Diodes · SOD-323F

1N4148WSF-7 from Diodes Incorporated, in a SOD-323F. 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	1	passive	Pin 1 is shown in the SOD323F package outline drawing on page 3, but the datasheet does not state whether it is the anode or the cathode.
2	2	passive	Pin 2 is shown in the SOD323F package outline drawing on page 3, but the datasheet does not state whether it is the anode or the cathode.
