2SB766A

Changjiang Electronics Tech (CJ) · Bipolar Transistors - BJT · SOT-89-3L

2SB766A from Changjiang Electronics Tech (CJ), in a SOT-89-3L. 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 PNP transistor; the datasheet specifies VBE(sat) of -0.85 V (min) to -1.2 V (max) at IC=-500mA, IB=-50mA, and VEBO of -5 V.
2 COLLECTOR passive Collector terminal; the datasheet limits are VCBO -60 V, VCEO -50 V, continuous IC -1 A, and collector power dissipation PC 500 mW.
3 EMITTER passive Emitter terminal; the datasheet limits the emitter-base voltage to VEBO -5 V.
