2N5551H-98

ALJ · Bipolar (BJT) · TO-92

2N5551H-98 from ALJ, 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 Emitter passive Emitter terminal of the NPN transistor; the datasheet limits emitter-base voltage VEBO to 6 V.
2 B passive Base terminal of the NPN transistor; the base drive is referenced to the emitter, with emitter-base breakdown voltage V(BR)EBO of 6 V minimum and maximum IC of 0.6 A.
3 C passive Collector terminal of the NPN transistor; the datasheet limits VCBO to 180 V, VCEO to 160 V, and collector current IC to 0.6 A.
