2SB370

      The 2SB370 is a kind of germanium PNP alloyed junction type which is designed for audio frequency output stage amplifier.It has some features as relatively large allowable collector dissipation in small dimension and linear dependency of current transfer ratio on collector current up to rated value.The transistor is effectively used as medium power output stage amplifiers of portable radios,car radio receivers,tape recorders and so on.
      What comes next is about the absolute maximum ratings of 2SB370.The V_CBO (Collector-base voltage) is -25 V.The V_CEO (Collector-emitter voltage) is -18 V and the V_CES (Collector-emitter voltage) is -25 V.The V_EBO (emitter-base voltage) is -12 V.The I_C (Collector Current) is -500 mA.The I_E (emitter Current) is 500 mA.The P_C (Collector Dissipation) is 200 mW.The T_stg (Storage Temperature Range) is from -55 to +85.The T_J (Junction Temperature) is 85.
      There are the electrical characteristics of 2SB370 at 25 ambient temperature.The minimum BV_CBX (collector-base breakdown voltage) is -25 V at I_C=-100 A,V_EB=-6 V.The maximum I_CBO (collector current) is -20A at V_CB=-12 V,I_E=0.The maximum I_EBO (emitter-base cutoff current) is -20 A at V_EB=-6 V,I_C=0.The maximum I_CEO (collector-emitter cutoff current) is -5 mA at V_CE=-18 V,R_BE=.The maximum I_CES (collector cutoff current) is -5 mA at V_CE=-25 V,R_BE=0.The minimum h_FE(collector cutoff current) is 70,the typical is 150 and the maximum is 300 at V_CE=-1 V,I_C=-150 mA.The typical h_fe (small signal current transfer ratio) is 110 at V_CE=-6 V,I_C=-1 mA,f=270 Hz.
