2SC3647G-S-AB3-R

UTC(Unisonic Tech) · Bipolar (BJT) · SOT-89

2SC3647G-S-AB3-R from UTC(Unisonic Tech), 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 B passive Base terminal of the NPN transistor; the datasheet specifies base drive via IB = 100 mA for the test point IC = 1 A (VBE(SAT) max 1.2 V).
2 C passive Collector terminal; maximum ratings are VCBO 120 V, VCEO 100 V and continuous collector current IC 2 A (pulse ICP 3 A).
3 E passive Emitter terminal; maximum emitter-to-base voltage VEBO is 6 V.
