BAT54SW-7-F

Diodes Incorporated · Schottky Barrier Diodes (SBD) · SOT-323-3

BAT54SW-7-F from Diodes Incorporated, in a SOT-323-3. 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 first Schottky diode (left diode in the top-view BAT54SW diagram); the series pair is rated 30 V VRRM and 200 mA continuous forward current.
2 K passive Cathode of the second Schottky diode (right diode in the top-view BAT54SW diagram); the series pair is rated 30 V VRRM and 200 mA continuous forward current.
3 CA passive Common node joining the cathode of the first diode to the anode of the second diode in the series BAT54SW configuration (top terminal in the diagram).
