2SC5085 2007-11-01 1 TOSHIBA Transistor Silicon NPN Epitaxial Planar Type 2SC5085 VHF~UHF Band Low Noise Amplifier Applications • Low noise figure, high gain. • NF = 1.1dB, |S21e|2 = 11dB (f = 1 GHz) Absolute Maximum Ratings (Ta = 25°C) Characteristics Symbol Rating Unit Collector-base voltage VCBO 20 V Collector-emitter voltage VCEO 12 V Emitter-base voltage VEBO 3 V Base current IB 40 mA Collector current IC 80 mA Collector power dissipation PC 100 mW Junction temperature Tj 125 °C Storage temperature range Tstg −55~125 °C Note: Using continuously under heavy loads (e.g. the application of high temperature/current/voltage and the significant change in temperature, etc.) may cause this product to decrease in the reliability significantly even if the operating conditions (i.e. operating temperature/current/voltage, etc.) are within the absolute maximum ratings. Please design the appropriate reliability upon reviewing the Toshiba Semiconductor Reliability Handbook (“Handling Precautions”/“Derating Concept and Methods”) and individual reliability data (i.e. reliability test report and estimated failure rate, etc).
