2SA1408

      The 2SA1408(TOSHIBA Transistor Silicon PNP Epitaxial Type (PCT Process)) is used in Color TV Vertical Deflection Output Applications, Color TV Class-B Sound Output Applications, which also is large collector current and collector power dissipation capability, recommended for vertical deflection output and sound output applications for line-operated TV, and for complementary to 2SC3621.
      Some parameters of 2SA1408 are got at Tc(=25°C), VCBO(Collector-base voltage)=-150V, VCEO(Collector-emitter voltage)=-150V, VEBO(Emitter-base voltage)=-6V, IB(Continuous base current)=-1.0A, IC(Continuous collector current)=-1.5A, PC(Collector power dissipation, Ta = 25°C)/PC(Tc = 25°C)=1.5/10W, Tstg(Storage temperature range)=-55 to 150°C, Tj(Junction temperature)=150°C. Some about the electrical properties are also got at Tc (25°C), ICBO(Collector cut-off current, VCB =-150V, IE = 0)=-0.1A(Max), IEBO(Emitter cut-off current, VEB = -6V, IC = 0)=-0.1A, hFE (1)(VCE = -1 V, IC = -10 mA, R: 60 to 120, O: 100 to 200)=60(min)/200(max), V CE (sat) (Collector-emitter saturation voltage, IC = -500 mA, IB = -50 mA)=-1.5 V, VBE(Base-emitter saturation voltage, VCE = -5 V, IC = -5 mA )=-0.5V(min)/-0.8(max)V, fT(Transition frequency, VCE = -5V, IC = -200mA)=15(Min)/50(Typ.)MHz, Cob(Collector output capacitance, VCB = -10 V, IE = 0, f = 1 MHz)=35(Max)pF.
      Using continuously under heavy loads (e.g. the application of high temperature/current/voltage and the significant change in temperature, etc.) may cause 2SA1408 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).
