AD-KTA1505-Y

Changjing · Bipolar Transistors - BJT · SOT-23

AD-KTA1505-Y 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, with VEBO rated at -5 V and IEBO at most -0.1 µA at VEB = -5 V.
2 EMITTER passive Emitter of the PNP transistor, with collector-emitter voltage VCEO rated at -30 V.
3 COLLECTOR passive Collector of the PNP transistor, rated for -500 mA continuous current and -35 V VCBO.
