YFW1012A-G

YFW · Bipolar (BJT) · SOT-223

YFW1012A-G from YFW, in a SOT-223. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 B input Base of the PNP transistor. Emitter-base breakdown voltage BVEBO = -5 V; base drive IB = -0.15 A used to achieve IC = -3 A saturation (VBE(on) = -1.2 V max).
2 C passive Collector of the PNP transistor (front-lead pin 2). Internally tied to the tab (pin 4). Collector-base breakdown BVCBO = -60 V, collector-emitter breakdown BVCEO = -50 V, IC(max) = -3 A, PC = 1 W.
3 E passive Emitter of the PNP transistor. Reference terminal for VCE and VBE; carries IE up to approximately -3 A in saturated operation.
4 C passive Collector tab (thermal pad) of the SOT-223. Electrically identical to pin 2; provides the primary thermal path to the PCB copper pour for dissipating up to 1 W.
