KTA1040D-Y-RTF

KEC Semicon · Bipolar (BJT) · TO-252-2(DPAK)

KTA1040D-Y-RTF from KEC Semicon, in a TO-252-2(DPAK). 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 BASE input Base terminal of the PNP transistor, with a base current rating of IB = -0.5 A (maximum) stated in the absolute maximum ratings.
2 COLLECTOR passive Collector terminal, rated for VCBO = -60 V, VCEO = -60 V and collector current IC = -3 A in the absolute maximum ratings.
3 EMITTER passive Emitter terminal, with the emitter-base voltage rating VEBO = -7 V stated in the absolute maximum ratings.
