8050D

ST Semtech · Bipolar (BJT) · TO-92

8050D from ST Semtech, in a TO-92. 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 Emitter passive Emitter terminal of the NPN transistor, with emitter-base breakdown V(BR)EBO of at least 6 V and VEBO rated at 6 V.
2 Base passive Base terminal, with base current IB rated at 100 mA maximum.
3 Collector passive Collector terminal, rated for VCBO 40 V, VCEO 25 V and collector current IC 800 mA.
