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. |
