The BFR91A from Planeta is an NPN silicon epitaxial transistor designed for low noise amplifier applications across the VHF, UHF, and CATV frequency bands. This small-signal transistor provides dynamic range and favorable current characteristics, offering superior quality and performance at a low cost.
Key electrical specifications include a typical transition frequency (fT) of 6.0 GHz at 30 mA, a low noise figure (NF) of 1.6 dB at 800 MHz, and a high power gain (GPS) of 13.0 dB at 800 MHz. The DC current gain (hFE) ranges from 50 to 300. Absolute maximum ratings specify a collector-emitter voltage (VCEO) of 12V and a collector current (IC) of 50 mA, with a total power dissipation (Ptot) of 300 mW.
This transistor is housed in a SOT-37 (TO-50) surface-mount package. The operating junction temperature range is -45°C to +70°C, with a maximum storage temperature of +150°C. The thermal resistance from junction to case is 400 °C/W.
Applications for the BFR91A include low-noise amplifiers in radio frequency circuits, particularly within the VHF, UHF, and CATV spectrums, where its combination of gain, low noise, and high frequency response is beneficial.
