BAW56WT1G

onsemi · Switching Diodes · SOT-323

BAW56WT1G from onsemi, in a SOT-323. 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 CATHODE passive Cathode of one of the two diodes in the common-anode dual switching diode (SC-70 Style 4 pin assignment).
2 CATHODE passive Cathode of the second diode in the common-anode dual switching diode (SC-70 Style 4 pin assignment).
3 ANODE passive Common anode shared by both diodes, per the SC-70 Style 4 pin assignment and the device marking diagram on page 1.
