BAV21HWF-7

Diodes Incorporated · Diodes - General Purpose · SOD-123F

BAV21HWF-7 from Diodes Incorporated, in a SOD-123F. 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 on the bar-marked side of the SOD123F package; the part blocks 250V reverse (VRRM/VR) and conducts 200mA average rectified current.
2 A passive Anode, the terminal opposite the cathode bar; forward voltage is 1.0V max at IF=100mA and 1.25V max at IF=200mA.
