BAW56WTQ

Yangzhou Yangjie Elec Tech · Switching Diodes · SOT-323

BAW56WTQ from Yangzhou Yangjie Elec Tech, 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 K1 passive Cathode of diode 1 in the dual common-anode BAW56WTQ, with 100V reverse breakdown and 150mA average forward current (single diode loaded).
2 K2 passive Cathode of diode 2 in the dual common-anode BAW56WTQ, with 100V reverse breakdown and 150mA average forward current (single diode loaded).
3 A passive Common anode of both diodes in the BAW56WTQ, shared by pins 1 and 2.
