BAT54CWQ-7-F

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

BAT54CWQ-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	A1	passive	Anode of the first Schottky diode (bottom-left pad in the top view); the part is rated for VR 30 V and IF 200 mA.
2	A2	passive	Anode of the second Schottky diode (bottom-right pad in the top view); the part is rated for VR 30 V and IF 200 mA.
3	K	passive	Common cathode of both Schottky diodes (top pad in the top view); the part is rated for VR 30 V and IF 200 mA.
