LBSS5250Y3T1G

LRC · Bipolar (BJT) · SOT-89

LBSS5250Y3T1G 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 PNP transistor; the emitter-base voltage VEBO is limited to -6 V.
2 C passive Collector of the PNP transistor, rated VCEO -50 V, VCBO -50 V and IC -2 A continuous (-4 A pulsed).
3 E passive Emitter of the PNP transistor, shown with the arrow pointing toward the base in the symbol.
