KRB551V-40-7-F

KUU · Schottky Diodes · SOD-323

KRB551V-40-7-F from KUU, 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 end marked with the color band; the datasheet gives a maximum DC blocking voltage of 40 V and a maximum forward current of 350 mA.
2 A passive Anode; the datasheet gives a forward voltage of 0.370 V at IF = 20 mA and 0.600 V at IF = 200 mA.
