2SB1386G-R-AB3-R

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

2SB1386G-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 of the PNP transistor; the datasheet lists Emitter-Base voltage VEBO as -6 V max.
2 C passive Collector of the PNP transistor; rated VCBO -30 V, VCEO -20 V, IC(DC) -5 A and IC(PULSE) -10 A.
3 E passive Emitter of the PNP transistor; the datasheet gives no separate rating for this pin beyond the VEBO -6 V limit.
