LBSS4350SY3T1G

LRC · Bipolar (BJT) · SOT-89

LBSS4350SY3T1G from LRC, in a SOT-89. 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 B input Base of the NPN transistor; the datasheet gives VEBO of 6 V maximum and VCBO of 60 V maximum.
2 C passive Collector of the NPN transistor; the datasheet gives VCEO of 50 V, IC of 3 A and ICP of 6 A (pulse) maximum.
3 E passive Emitter of the NPN transistor, shown with the arrow pointing out of the device in the symbol; VEBO is 6 V maximum.
