2SC3647G-R-AB3-R

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

2SC3647G-R-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 input Base terminal of the NPN transistor; the datasheet rates emitter-to-base voltage VEBO at 6 V and gives VBE(SAT) of 0.85 V typ and 1.2 V max at IC = 1 A, IB = 100 mA.
2 C passive Collector terminal; the datasheet rates VCBO at 120 V, VCEO at 100 V, collector current IC at 2 A and pulse current ICP at 3 A, with collector dissipation PC of 500 mW.
3 E passive Emitter terminal; the datasheet gives VEBO of 6 V and an emitter cutoff current IEBO of 100 nA max at VEB = 4 V.
