The Philips BF547 is a silicon NPN transistor in a SOT-323 (S-mini) plastic package. It is designed for high-frequency applications, offering a transition frequency of up to 1.6 GHz.
This transistor is suitable for stable oscillator operation, featuring a high current gain and good thermal stability. Its primary intended applications include mixers, oscillators, and IF amplifiers in UHF and VHF tuners.
Key electrical characteristics include a collector-emitter voltage (VCEO) of 20V and a collector current (IC) of up to 50mA. The feedback capacitance (Cre) is typically 1 pF at 1 MHz, and the maximum unilateral power gain (GUM) is -20 dB at 100 MHz.
The BF547 is surface-mounted and operates within a junction temperature range of -65 to +150 °C. Its thermal resistance from junction to soldering point is 290 K/W.
