L8550HQLT1G

LRC · Bipolar (BJT) · SOT-23

L8550HQLT1G from LRC, in a SOT-23. 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 BASE input Base terminal of the PNP transistor, where the emitter-base breakdown voltage is -5 V minimum at IE=-100 µA and the emitter cutoff current is -150 nA maximum at VEB=-4 V.
2 EMITTER passive Emitter terminal of the PNP transistor, rated for a collector current of -1500 mAdc maximum and a junction and storage temperature range of -55 to +150 °C.
3 COLLECTOR passive Collector terminal of the PNP transistor, rated for VCEO of -25 V and VCBO of -40 V, with total device dissipation of 225 mW on an FR-5 board or 300 mW on an alumina substrate at TA=25°C.

CAD (KiCad official)

  • Symbol: L8550HQLT1G
  • Footprint: Package_TO_SOT_SMD:SOT-23
  • 3D model: SOT-23 (KiCad packages3D, STEP)
  • 3D model files: l8550hqlt1g-etched.step / l8550hqlt1g-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); l8550hqlt1g.step / l8550hqlt1g.glb are the bare package body.
