The BF457 is an NPN high-voltage transistor designed for applications such as video output stages in color and black-and-white television receivers. It is housed in a TO-126 or SOT32 plastic package.
Key electrical characteristics include a collector-emitter voltage (VCEO) of 160V and a peak collector current (ICM) of 300mA. The DC current gain (hFE) ranges from 2 to 6 under typical conditions (IC = 30mA, VCE = 10V). The transition frequency (fT) is 90 MHz at IC = 15mA and VCE = 10V.
Thermal specifications include a total power dissipation (Ptot) of 6W at a mounting base temperature (Tmb) of 90°C. The thermal resistance from junction to mounting base (Rth j-mb) is 10 K/W.
This transistor is intended for use in applications requiring high voltage handling capabilities within the specified limits.
