The BF470 is a PNP high-voltage transistor manufactured by Telefunken. It is designed for applications requiring high voltage handling, with a collector-emitter voltage (VCEO) of 250V and a collector-base voltage (VCBO) of 250V.
Key electrical characteristics include a minimum DC current gain (hFE) of 50 and a transition frequency (fT) of 60 MHz. The feedback capacitance (Cre) is notably low at a maximum of 1.8 pF, making it suitable for sensitive circuits. The device can handle a peak collector current (ICM) of 100 mA and a continuous collector current (IC) of 50 mA.
This transistor is housed in a TO-126 (SOT32) plastic package, designed for through-hole mounting. It has a total power dissipation (Ptot) of 1.8W at a mounting base temperature (Tmb) of up to 114 °C. Thermal resistance from junction to mounting base (Rth j-mb) is 20 K/W.
Applications for the BF470 include class-B video output stages in television receivers and high-voltage IF output stages. Its NPN complements are the BF469 and BF471.
