8550-D

Foshan Blue Rocket Elec · Bipolar (BJT) · TO-92

8550-D from Foshan Blue Rocket Elec, 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 Collector passive Collector terminal of the PNP transistor; the datasheet gives absolute maximum ratings of VCBO -40 V, VCEO -25 V, continuous IC -1.5 A (ICM -3 A for t≤1 ms) and PC 1.0 W.
2 Base passive Base terminal of the PNP transistor; the datasheet gives a maximum continuous base current IB of -0.5 A and VEBO of -6.0 V.
3 Emitter passive Emitter terminal of the PNP transistor; the emitter-to-base rating is VEBO -6.0 V.
