The BF495 is an NPN medium frequency transistor manufactured by Philips Semiconductors, housed in a TO-92 or SOT54 plastic package. This component is designed for high-frequency (HF) applications, including radio and television receivers, FM tuners, low noise AM mixer-oscillators, and IF amplifiers in AM/FM receivers.
Key electrical characteristics include a collector-emitter voltage (VCEO) of up to 20V and a peak collector current (ICM) of up to 30mA. The DC current gain (hFE) for the BF495 ranges from 35 to 125 at 1mA collector current and 10V collector-emitter voltage. Its transition frequency (fT) is a minimum of 120 MHz under specified test conditions.
The transistor operates within a temperature range of -65°C to 150°C, with a total power dissipation of up to 300mW at 25°C ambient temperature. The thermal resistance from junction to ambient is 420 K/W when mounted on an FR4 printed-circuit board.
This component is suitable for various RF circuits requiring a reliable NPN transistor. Its specifications make it a good choice for signal amplification and oscillation in radio frequency designs.
