MMBT8099LT1G

onsemi · Bipolar (BJT) · SOT-23

MMBT8099LT1G from onsemi, 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 passive Base terminal of the NPN amplifier transistor; the datasheet gives the emitter-base limit of VEBO 6.0 Vdc and the device is rated for 500 mAdc continuous collector current.
2 EMITTER passive Emitter terminal of the NPN amplifier transistor, with the emitter-base breakdown voltage V(BR)EBO of 6.0 Vdc minimum and the 500 mAdc continuous collector current rating referenced to this device.
3 COLLECTOR passive Collector terminal of the NPN amplifier transistor, rated for VCEO of 80 Vdc and VCBO of 80 Vdc with a continuous collector current of 500 mAdc.
