KTA1504Y

Changjing · Bipolar Transistors - BJT · SOT-23

KTA1504Y from Changjing, in a SOT-23. 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 of the PNP transistor; the datasheet gives VEBO of -5 V and IB of -10 mA in the saturation test condition.
2 EMITTER passive Emitter of the PNP transistor; the datasheet gives emitter-base breakdown voltage of -5 V at IE=-100 µA.
3 COLLECTOR passive Collector of the PNP transistor; the datasheet gives VCEO of -50 V and a maximum collector current IC of -150 mA.
