2SC3303-Y

TOSHIBA · Bipolar (BJT) · TO-251-3

2SC3303-Y from TOSHIBA, in a TO-251-3. 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 B input Base; emitter-base voltage limited to 7 V (VEBO) and base current to 1 A (IB).
2 C passive Collector, also the heatsink tab; VCEO 80 V, VCBO 100 V, IC 5 A DC and 8 A pulsed.
3 E passive Emitter, the common terminal of the NPN transistor.
