K1N5817HW-7-F

KUU · Schottky Diodes · SOD-123

K1N5817HW-7-F from KUU, in a SOD-123. 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 terminal at the cathode band end of the SOD-123 package; reverse voltage limit is 20 V for K1N5817HW (VRRM 20 V, 30 V for K1N5818HW, 40 V for K1N5819HW).
2 A passive Anode, the terminal opposite the cathode band; average rectified current 1 A, non-repetitive peak surge 10 A (8.3 ms), forward voltage max 0.45 V at 1 A for K1N5817HW.
