2SB1424-R

Foshan Blue Rocket Elec · Bipolar Transistors - BJT · SOT-89

2SB1424-R from Foshan Blue Rocket Elec, in a SOT-89. 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 silicon PNP transistor in the SOT-89 plastic package, used for general purpose amplification.
2 Collector passive Collector terminal; the datasheet limits are VCBO -20 V, VCEO -20 V, continuous collector current IC -3.0 A and collector power dissipation PC 0.6 W.
3 Emitter passive Emitter terminal of the silicon PNP transistor; the emitter-to-base breakdown voltage VEBO is -6.0 V.
