KTN2907AS-RTK

KEC Semicon · Bipolar (BJT) · SOT-23

KTN2907AS-RTK from KEC Semicon, 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 EMITTER passive Emitter of the PNP transistor; emitter-base breakdown V(BR)EBO is -5 V minimum at IE=-10 µA, and absolute emitter-base voltage VEBO is -5 V.
2 BASE passive Base of the PNP transistor; VBE(sat) is at most -1.3 V at IC=-150 mA, IB=-15 mA and at most -2.6 V at IC=-500 mA, IB=-50 mA.
3 COLLECTOR passive Collector of the PNP transistor; absolute maximum ratings are VCBO -60 V, VCEO -40 V (KTN2907S) / -60 V (KTN2907AS), and IC -600 mA, with PC 350 mW at Ta=25 °C.
