技术问答

Central Semiconductor(美国中央半导体公司，简称Central)公司是世界顶级分立半导体制造商，Central推出的BC559C是一款硅PNP小信号晶体管，采用外延平面工艺制造，实物如图1所示，专为通用放大器应用而设计。

在工作温度为25℃时，BC559C硅PNP小信号晶体管的集电极-基极电压和集电极-发射极电压的最大额定值均为30V，发射极-基极电压的最大额定值为5.0V，集电极持续工作电流为100mA。其峰值集电极电流、峰值基极电流、峰值发射极电流的最大额定值均为200mA。BC559C的功耗P_D最大额定值为500mW，热阻为150°C/W，存储和工作温度范围为-65~150℃，操作结温最高额定值为150℃，较宽的工作温度范围可以保证其在恶劣的环境下也可以实现可靠的性能，从而能够满足工业级工作温度要求。

BC559C硅PNP小信号晶体管的集电极-基极截止电流I_CBO极低，在V_CB=20V，工作温度为25℃时为15nA。BC559C的饱和压降V_CE(SAT)在I_C=10mA, I_B=0.5mA时，最大值为300mV。BC559C的特征频率f_T在V_CE=5V、I_C=10mA、f=35MHz的条件下，可达150MHz。其输出电容C_OB典型值仅为4.5pF，可减少信号衰减和失真，保持信号的完整性。

BC559C硅PNP小信号晶体管的直流放大系数h_FE在V_CE=5.0V, I_C=2.0mA时，最小值为420，最大值为800。它的噪声系数NF在V_CE=5.0V, I_C=0.2mA, R_G=2.0kΩ,B=200Hz, f=1.0kHz的条件下，典型值为1.0dB,最大值为4.0dB。
