1N4148SOD-323

Shenzhen Jinkaisheng Elec · Switching Diodes · SOD-323

1N4148SOD-323 from Shenzhen Jinkaisheng Elec, in a SOD-323. 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, the banded end of the package; the diode withstands VRRM 75 V repetitive peak reverse voltage (VRSM 100 V non-repetitive) and the band indicates cathode.
2 A passive Anode, the unbanded end of the package; continuous forward current IO is 150 mA, repetitive peak IFRM 300 mA and surge IFSM 2 A (1 us pulse).
