PT23T3906

Shanghai Prisemi Elec · Bipolar Transistors - BJT · SOT-23

PT23T3906 from Shanghai Prisemi Elec, 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 of the PNP transistor; breakdown limits are V(BR)EBO -6.0 V (emitter-base) and V(BR)CBO -60 V (collector-base).
2 Emitter passive Emitter of the PNP transistor; emitter-base breakdown voltage V(BR)EBO is -6.0 V at IE=-10uA.
3 Collector passive Collector of the PNP transistor; collector-emitter breakdown voltage V(BR)CEO is -40 V at IC=-1.0mA, with total device dissipation of 150 mW at TA=25°C.
