LBTN180Y3T1G

LRC · Bipolar (BJT) · SOT-89

LBTN180Y3T1G 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; base current IB is limited to 0.3 A (peak 0.3 A, tp≤1 ms) and emitter-base voltage VEBO to 5 V.
2 C passive Collector of the NPN transistor (also the package tab per the SOT89 outline); VCEO 80 V, VCBO 100 V, IC 1 A (ICM 2 A peak, tp≤1 ms).
3 E passive Emitter of the NPN transistor, shown with the arrow on the pin 3 side of the schematic symbol; VEBO is limited to 5 V.
