LBAT54SWT1G

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

LBAT54SWT1G from LRC, 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	ANODE	passive	Anode terminal of the first diode in the dual series Schottky configuration, with the device rated for 30 V reverse voltage and 200 mA DC forward current.
2	CATHODE	passive	Cathode terminal of the second diode in the dual series Schottky configuration, with the device rated for 30 V reverse voltage and 200 mA DC forward current.
3	CATHODE/ANODE	passive	Common internal junction between the two series Schottky diodes, connecting the cathode of one diode to the anode of the other.
