MT4S03A TOSHIBA Transistor Silicon NPN Epitaxial Planar Type MT4S03A VHF~UHF Band Low Noise Amplifier Applications • Low noise figure: NF = 1.4dB (f = 2 GHz) • High gain: Gain = 9dB (f = 2 GHz) Unit: mm Absolute Maximum Ratings (Ta = 25°C) Characteristics Symbol Rating Unit Collector-base voltage VCBO 10 V Collector-emitter voltage VCEO 5 V Emitter-base voltage VEBO 2 V Base current IC 40 mA Collector current IB 10 mA Collector power dissipation PC 150 mW Junction temperature Tj 125 °C Tstg −55~125 °C Storage temperature range Note: Using continuously under heavy loads (e.g. the application of high JEDEC ― temperature/current/voltage and the significant change in JEITA ― temperature, etc.) may cause this product to decrease in the reliability significantly even if the operating conditions (i.e. TOSHIBA 2-3J1C operating temperature/current/voltage, etc.) are within the Weight: 0.012 g (typ.) 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).
