BAT400D-7-F

Diodes Incorporated · Schottky Diodes · SOT-23

BAT400D-7-F from Diodes Incorporated, in a SOT-23. 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 A passive Anode of the single Schottky diode, shown on the bottom-left lead of the top-view device schematic (40V VRRM, 0.5A average rectified current).
2 NC unconnected No internal connection; the bottom-right lead of the device schematic has no diode connection.
3 K passive Cathode of the single Schottky diode, shown on the top lead of the device schematic (40V VR DC blocking voltage).
