Infineon Technologies AG Bipolar Transistor, General Purpose Transistor BC847CW

BC847CW is an NPN silicon AF transistor in an SOT323 package, designed for AF input stages and driver applications. It has a collector-emitter voltage rating of 45 V, a collector current limit of 100 mA, and a total power dissipation of 250 mW at ambient temperatures up to 124 °C. The device offers high current gain with hFE groups from 420 to 800 at I_C = 2 mA and V_CE = 5 V, low collector-emitter saturation voltage up to 250 mV at I_C = 10 mA and I_B = 0.5 mA, and low noise with a figure of merit of 1.2 to 4 dB between 30 Hz and 15 kHz. It is RoHS compliant and does not meet AEC-Q101 qualification. The thermal resistance from junction to soldering point is ≤105 K/W. Transition frequency is 250 MHz at I_C = 10 mA and V_CE = 5 V.
