BC807-40LT3G

onsemi · Bipolar Transistors - BJT · SOT-23

BC807-40LT3G 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 input Base terminal of the PNP transistor; base-emitter on voltage VBE(on) is at most -1.2 V at IC = -500 mA and VCE = -1.0 V.
2 EMITTER passive Emitter terminal of the PNP transistor; emitter-base breakdown voltage V(BR)EBO is at least -5.0 V at the specified test current.
3 COLLECTOR passive Collector terminal of the PNP transistor; collector-emitter voltage VCEO is -45 V and continuous collector current IC is -500 mA.
