LBSS4250Y3T1G

LRC · Bipolar (BJT) · SOT-89

LBSS4250Y3T1G 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; DC current gain 180-450 at VCE = 2 V, IC = 50 mA, and emitter-base voltage limited to 6 V.
2 C passive Collector of the NPN transistor (also connected to the package tab); VCEO 50 V, VCBO 50 V, IC 2 A continuous and 4 A pulsed.
3 E passive Emitter of the NPN transistor; VEBO maximum 6 V, with the emitter arrow shown on pin 3 in the schematic symbol.
